Lump Aluminum Strontium Master Alloy (Alsr3.5 5 10 15 20 Alloy)

With the help of diligent and adept professionals, our organization is prominent Exporter, Manufacturer & Supplier of Aluminum Strontium Master Alloy (AlSr3.5 5 10 15 20 Alloy) in Shanghai, Shanghai, China.
Master alloys are semi-finished products, and can be formed in different shapes. They are pre-alloyed mixture of alloying elements. They are also known as modifiers, hardeners, or grain refiners based on their applications. They are added to a melt to achieve the disired result. They are used instead of a pure metal because they are very economical and save energy and production time.
