Product Description
Al-Sr MASTER ALLOYSThe eutectic silicon and the hypoeutectic silicon use AISI to proceed the modification,which can transform the thick massive eutectic silicon to the tiny fibrous structure, hinder the growth of silicon so as to improve the mechanical properties of the alloys.(change the fine pores into micropores.)
Product name: AlSr3.5 , AlSr5, AlSr10, AlSr10 Ti1 B0.2 AlSr15
Adding amount: The add quantity of Sr depends on the content of silicon in aluminum alloy. The metamorphism of eutectic alloy is harder than the hypoeutectic eutectic alloy, so the addition amount of AlSi12 alloy is higer, the content of the Sr may be as high as 0.03%,If produce the high quality casting products, we recommend using both alterative and grain refiner.Aluminum Alloy Grain REFINERS AL-Ti-B alloyControl the grain refining effect is a key link of aluminum casting. The early stage of the aluminum alloys if want to obtain the effect of grain refining, the first step is bringing in the titanium, and then add chemical salt into the molten aluminum(KBF4 and K2TiF6).Today, these operations have been replaced by adding Al-Ti-B alloy
The Al-Ti-B model and adding amount depend on many factors. These factors include alloy model, recycling aluminum proportion, grain size requirements, the production process, etc.
At the soonest 15 seconds can reach the highest refining efficiency. Silicon Metal
Silicon Metal, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. It is a product made by smelting quartz and coke in an electric furnace. The main element silicon content is about 98%, and the remaining impurities are iron and aluminum, Calcium, etc.Silicon Metal Detail:
