Aluminum forgings are objects made of metal that undergo plastic deformation under pressure to shape the desired shape or appropriate shrinkage force. This type of pneumatic paradigm is ultimately achieved using a hammer or pressure. The casting process has constructed intricate particle structures and improved the physical properties of metals. In the fantasy use of components, a correct imagination can make the particle flow at the target of the main pressure.
There are many heating methods for metal heat treatment, and early on, charcoal and coal were used as heat sources, followed by the application of liquid and gas fuels. Electrical applications make heating easy to control and environmentally friendly. These heat sources can be used for direct heating, as well as indirect heating through molten salts or metals, and even floating particles. Below, aluminum alloy forging manufacturers will take us to understand the purpose and effectiveness of quenching and annealing in heat treatment of aluminum forgings.
1、 Purpose and Application of Quenching:
1. Improve the strength of the parts and maintain high plasticity.
2. Improve the corrosion resistance of aluminum castings working below 100 ℃;
Used for aluminum castings under dynamic load impact.
Explanation: When aluminum castings require high strength, they need to be stored for at least 4 days and nights from quenching to mechanical processing. T4 also represents quenching and natural aging, with a quenching temperature of about 500~535 ℃, and an aluminum magnesium alloy quenching temperature of about 435 ℃.
2、 Annealing purpose and use:
1. Eliminate the casting stress of aluminum castings and work hardening caused by mechanical processing.
2. Improve shaping.
Used for aluminum alloy castings that require stable dimensional requirements during use. Suitable for casting aluminum alloy ZL101, ZL102。
Explanation: The annealing temperature is approximately 280~300 ℃, and the insulation time is 2~4h. Generally, aluminum castings undergo this treatment after casting or rough machining.
Aluminum forgings require each piece to be free from any porosity, excess space, inclusions, or other defects. The components consumed by this method have a high ratio of strength to weight. These components are commonly used in aircraft structures. Formally, aluminum forgings can stretch in length and shrink in cross-section; Shrinkable length, extendable cross-section; Adjustable length, adjustable cross-section. So, it is widely influenced in various industries and suitable for fields such as machinery, metallurgy, engineering, etc
