Electroless Nickel Plating (TM103)

TM103 ENElectroless Nickel (EN) plating at its best. Techmetals’ TM 103 offers a high phosphorus content (9%+), which is optimal for corrosion resistance, as well as increased hardness and lubricity.

It has a uniform deposit (within +/- .0001, dependent upon thickness requirement), which actually encapsulates the part and a hardness of 47-52 Rockwell as plated. TM 103 is heat treatable up to 65-70 Rockwell. This finish is free of heavy metal contaminants – which equates to a consistent application, free of cracks and divots.

Parts receive superior corrosion resistance with TM 103, when compared to that of standard EN coating. A one mil thick coating, it has shown no rust after 1,000 hours in a salt spray test and a coefficient of friction of 0.4 μ.
