Advantages of STRONTIUM ALUMINUM ALLOY

Strontium aluminum alloy is an excellent alloy modifier developed in China in recent years. It is mainly used for the modification of hypoeutectic and eutectic aluminum-silicon alloys. Its modification type is equivalent to the traditional sodium element, but it has the following significant advantages over sodium: 1.1 The strontium metamorphism has a long effective period, up to 6-8 hours or more, and it still has a metamorphic effect after 4 to 5 remelting times. It can meet the needs of long-lasting low-pressure casting and metal mold casting, and is especially suitable for pouring large castings and continuous production.
