KBM Affilips produces a suite of copper-based master alloys for the brass and copper industry. The range of alloys offered by KBM Affilips includes Copper-Zirconium, Copper-Boron, Copper-Manganese, and Copper-Iron.
A common feature of the aforementioned alloys is that these alloys dissolve better when compared to the corresponding pure metals. Copper Phosphorus (CuAs) master alloy is one such material supplied by KBM Affilips.

Applications of CuP Master Alloys
KBM Affilips supplies CuP master alloys in waffle plate form. CuP master alloys are generally utilized for deoxidizing copper and copper alloys. Even though there are many other deoxidants available, phosphorus has demonstrated to be the most economical.
CuP master alloys also serve as an alloying agent into order to add a certain amount of phosphorus in copper alloys, including phosphor bronze and many different brazing alloys. The addition of phosphorus increases the fluidity of the metal.
CuP8 master alloy is used in the aluminum industry to treat hypereutectic AlSi foundry alloys for controlling the morphology and size of the solidifying primary silicon phase in order to increase the machinablity, wear resistance and toughness of the alloy. When CuP master alloys are employed for deoxidation applications, obtaining a residual phosphorus level of 0.010% to 0.015% is a common practice for preventing reoxidation, especially during the casting process.
CuP master alloys serve as an efficient deoxidant for Copper-Lead-Tin, Copper-Tin-Zinc, and Copper-Tin casting alloys. Nevertheless, they cannot be used for deoxidizing high conductivity copper because phosphorus is detrimental to electrical conductivity.
Moreover, it is not possible to use them for copper-nickel alloys due to the fact that the formation of a low melting phase by phosphorus leads to grain boundary embrittlement. KBM Affilips produces CuP master alloys at its specialized plant in an environmentally sound manner.
