AEROSPACE
MATERIALS USED IN AEROSPACE INDUSTRY
The aerospace industry demands materials that offer exceptional strength, durability, and resistance to various stressors such as heat, corrosion, and wear. For castings specifically, the materials used need to meet stringent aerospace standards for performance and safety. Below are some of the commonly used key materials:
1. Aluminium Alloys
Applications: Structural components, engine components, gearboxes components, and turbines.
Benefits: High strength-to-weight ratio, excellent corrosion resistance, and good thermal conductivity.
2. Titanium Alloys
Applications: Jet engine components, structural frames for high-speed aircraft, and landing gear.
Benefits: Exceptional strength, lightweight, superior corrosion resistance, and the ability to withstand high temperatures.
3. Nickel-based Super Alloys
Applications: Turbine blades, exhaust systems, and other engine components exposed to high temperatures.
Benefits: High-temperature strength, excellent mechanical properties at elevated temperatures, and good oxidation resistance.
4. Stainless Steel Alloys
Applications: Landing gear, fasteners, and fuel tanks.
Benefits: Strong, resistant to corrosion and oxidation, and capable of performing well at high temperatures.
5. Magnesium Alloys
Applications: Gearboxes, seating components, and interior parts of aircraft.
Benefits: Lightest of all structural metals, good stiffness, and strength-to-weight ratio.
6. Cobalt Alloys
Applications: Turbine discs and blades, exhaust nozzles, and other components requiring wear resistance.
Benefits: Wear resistance, strength at high temperatures, and resistance to thermal shock.
7. Beryllium Alloys
Applications: Optical and satellite components, avionics, and aerospace electronic equipment.
Benefits: High stiffness, excellent dimensional stability across temperature ranges, and lightweight.
8. Carbon Steel
Applications: Fasteners, fittings, certain landing gear components, and internal structural components.
Benefits: Excellent strength, wear resistance, and cost-effectiveness, suitable for areas where its weight and corrosion resistance are manageable.
Each of these materials brings specific properties that make them ideal for various applications within the aerospace industry. The choice of material for a particular casting depends on the component’s function, the environmental conditions it will face, and the performance requirements set by aerospace standards. Advances in material science continue to drive the development of new alloys and composites that further enhance the capabilities and efficiency of aerospace components. No matter what materials we use, we strictly follow the quality standards such as ISO 9001:2005 and AS 9100, we only offer parts that of highest quality possible and are inspected by our supply partners and ourselves in the UK.
MANUFACTURING TECHNIQUES USED IN AEROSPACE INDUSTRY
The aerospace industry relies on a variety of manufacturing and metalworking applications to produce the complex and high-performance components required for aircraft and spacecraft. These processes are critical for ensuring the safety, reliability, and efficiency of aerospace vehicles. Here are some typical manufacturing and metalworking techniques used in the aerospace industry:
1. Casting
Casting processes, including investment casting and die casting, are used to create complex metal components with high precision. This method is suitable for parts like turbine blades, engine housings, and other components that require intricate shapes and detailed geometries. As a manufacturing solutions provider and aerospace parts supplier, we offer investment casting, die casting, and shell moulding parts and components of highest quality from our ISO 9001 and AS 9100 accredited suppliers in China and Taiwan.
2. Forging
Forging, including closed-die and open-die forging, is utilised to produce parts that need exceptional strength and durability, such as landing gear components, engine mounts, and structural elements. Forging ensures superior mechanical properties by aligning the metal grain structure with the part geometry. We provide forgings for these critical components in the aerospace industry for over 30 years.
3. Machining
Precision machining operations, including CNC milling, turning, and EDM (Electrical Discharge Machining), are fundamental for shaping aerospace components to exact specifications. These processes are used for critical parts like engine components, fasteners, and structural brackets, where tight tolerances and surface finishes are required. A & M Manufacturing Company Ltd offers all types of precision machining service including post casting/forging machining and machining from solid metal.
4. Sheet Metal Fabrication
Sheet metal fabrication involves forming, cutting, and joining metal sheets to create components such as fuselage panels, wing skins, and ductwork. Techniques like bending, stamping, and welding are employed to produce lightweight, durable structures.
5. Additive Manufacturing (3D Printing)
Additive manufacturing is used for prototyping and producing complex components that would be difficult or impossible to make with traditional methods. It’s particularly valuable for lightweight structures, custom tooling, and components with internal channels or lattice structures for weight reduction.
6. Heat Treatment
Heat treatment processes, such as annealing, quenching, and tempering, are applied to metal parts to enhance their mechanical properties, including strength, hardness, and resistance to fatigue. This is crucial for components subjected to extreme operational stresses.
7. Surface Treatment
Surface treatments, including anodizing, coating, and plating, are used to improve corrosion resistance, wear resistance, and thermal properties of aerospace components. These treatments also serve aesthetic purposes and can help reduce friction.
8. Inspection and Quality Control
Advanced inspection and quality control methods, including X-ray, ultrasonic testing, and coordinate measuring machines (CMMs), are essential to ensure that aerospace components meet stringent safety and performance standards. At A & M Manufacturing Company Ltd, we strictly implement total quality management programs and utilise statistical process control at every stage of the manufacturing process, ensuring each component meets the highest quality standard and customers’ requirements.
These manufacturing and metalworking procecsses and techniques enable the aerospace industry to produce the sophisticated and reliable components necessary for the demanding environments of air and space travel.
AEROSPACE INDSUTRY APPLICATIONS
The aerospace industry relies on precision-engineered components for aircraft and spacecraft, utilising specific materials for their unique properties.
Turbine blades are made from nickel-based superalloys, vital for withstanding extreme temperatures in propulsion systems. Engine housings, crafted from aluminum or titanium alloys, protect critical engine parts while minimising weight. Stainless steel fuel system valves ensure efficient fuel flow with their corrosion resistance.
Landing gear components, including struts and wheel assemblies, are forged from high-strength steel or titanium to handle the significant loads of takeoff and landing. Structural brackets and fasteners, made from aluminum alloys or high-strength alloys, secure the aircraft’s framework, providing support and maintaining integrity under flight conditions.
Fuselage panels and wing skins, often fabricated from aluminum or advanced composites, define the aircraft’s aerodynamics and endure aerodynamic forces. Control surfaces like ailerons and flaps, crucial for maneuvering, leverage lightweight materials for effective operation.
These components highlight the industry’s need for materials like superalloys, aluminium, titanium, and stainless steel, chosen for their strength, durability, and lightweight properties, ensuring aerospace vehicles meet rigorous safety and performance standards.
