AlSr is used to add alloy element and adjust chemical composition of alloy when melting. AlSr is an excellent modifying agent to aluminum alloys; its modifying operation has long-effect, stability in remelting and anti-decay properties. It has no pollution, no erode effects. AlSr alloy is a new and indispensable modifying material in the field of auto manufacture, aluminum alloy wheel of motorbike, and superior aluminum casting in war industry.

Used as modifying agent,grain fefiner when casting AlSi alloy and general casting pieces. It's mainly used in grain refining of Al and Aluminum alloy to improve their performance and superficial quality.It is convenient to add and only small quantity can reach obvious efficacy. It's broadly used in field of aluminum casting, aluminum cable, aluminum foil, and so on.

Additives  is to adjust and compound the content of element in aluminum alloys smelting.

Salt is white or light grey powder which dissolves in water. Above 730 ℃ can give out fluorine hydride with water reaction, slow-moving dissolves in strong acid and gives out fluorine hydride. It is used as flux in Al and Al alloy rivet welding, glass, porcelain and ceramics industry.

Wheel is our new project, colorful fashion is our major character.
