1. Reinforcement solution

Add alloy elements (Si, CU, MG, Zn, Mn, Ni, etc.) to pure aluminum to generate aluminum -based solids, thereby increasing the mechanical property of aluminum alloy;

2. Time enhancement

The solid solution of alloy elements in aluminum decreases with the temperature. The saturated aluminum solid solid solution is obtained by heating to a certain temperature, maintenance and quenching. The saturated aluminum solid solid solution is placed at room temperature for a period of time or heated to a certain temperature. Over time, its strength and hardness increase, and the plasticity and toughness are reduced. The aging of aging at room temperature is called natural aging. The heating aging of non -standard metal stamping parts is called artificial aging;

3. Evergreen reinforcement

When the alloy element exceeds its extreme solubility, these alloy elements and aluminum or elements will form a hard and crunchy metal inter -compound, which will hinder the movement of alloys and bits, reducing strength, hardness, plasticity, and toughness;

4. Severly treatment

When the alloy crystals, add nutritional elements (titanium, 锆, 铍, 锶, rare earth, etc.) as a crystal nucleus, refine the grain grains, and improve the strength and plasticity of the alloy;

Add a small amount of sodium or sodium salt to the aluminum alloy liquid as a modified agent and modify it. Fine crystals can significantly improve their strength and plasticity.

5. Cold processing hardening

Metal materials deform at the re -crystallization temperature, and the materials are enhanced after deformation. The level of reinforcement changes with the degree of deformation, deformation temperature and material characteristics. When high -quality car hardware parts are cold and deforming at the same temperature, the greater the deformation of the same material, the greater the intensity. Anti -rust aluminum alloy and pure aluminum cannot be treated with heat treatment.
