Copper Tin alloy plating (metallization)

Copper-tin alloy plating is an alternative deposit of nickel plating and can be applied as a new anode electrode material.
A copper-tin alloy with a high tin content is called "speculum alloy". We provide the alloy plating, which tin content is from 30 to 70 wt.%.
This alloy was initially attempted as a material for reflectors. However, there was a problem such as the reflectance decreases due to oxidation. On the other hand, speculum alloy has been noted again as a new material for alternative deposit of nickel, since nickel may cause metal allergies. It can also be used for an anode material of lithium battery.

Note: Presently, experimental trial at our technical center only.
