Aluminium Alloy ADC12 Mechanical and Chamical introduction

ADC= Aluminum-Alloy Die Castings

ADC 12 is one style Japan Aluminium alloy casting material(JIS ADC12),ADC12 is equivalent to China’s domestic aluminium alloy code YL113, and the alloy grade is YZAlSi11Cu3. America Aluminium alloy code A384

aluminium alloy adc12 specification

The commonly used die-casting aluminum alloy is ADC12. Due to its good die-casting properties, it is suitable for thin casting parts. Its specific features are as follows:

1. Aluminium thermal conductivity, electrical conductivity and cutting performance of aluminum alloy die-casting are good.

2. The aluminum alloy shrinks less, so it has good filling performance.

3. The aluminum alloy has small density and high strength. The ratio of tensile strength to density is 9-15. It also keeps good when working at high temperature or low temperature. Mechanical properties.

4. Aluminum alloy has good corrosion resistance and oxidation resistance.
