Other Designations: Silicon aluminum(Al/Si) alloy, AlSi50 alloy, Si/Al alloy, Al-50%Si controlled expansion alloy.

• AlSi50(Al-50%Si) alloy can be used as substrates for RF circuits and microwave;
• AlSi50(Al-50%Si)) alloy replacement titanium in Space and Airborne system;
• AlSi50(Al-50%Si)) alloy can be chosen as radar housing replacement Kovar alloy;
• Al-50%Si controlled expansion alloy also can be used as transmit and receive modules.

Applications
