Automotive transmmision components must withstand repeated contact and friction, vibration, impact, corrosion, and dimensional changes throughout their service life. These demanding operating conditions require metal components with a balanced combination of high strength, hardness, wear resistance, corrosion resistance, dimensional stability, and long-term durability.
Conventional material choices for medium-sized transmission castings often include lightweight aluminum alloys such as A380, A356, and ADC12. However, when the component requires a combination of intricate geometry, good surface quality, wear resistance, and efficient mass production, engineers may consider ZA-12 zinc-aluminum alloy as an alternative material.
ZA-12 belongs to the zinc-aluminum alloy family, and contains approximately 12% aluminum, combines higher strength and hardness, corrosion resistance, excellent surface quality with high precision dimension accuracy. Through cold chamber die casting technique, high volume production of high quality automotive transmmision components will be completed by manufacturers.
