code:en-999
name:en-999 hi-phos electroless nickel plating process
1. the phosphorus content in deposits is up to 10.5-12%. it is adapted for high anti-corrosion products.
2. semi-bright, non-magnetic, no fine pores, low stress, especially good for emi shading plating, such as computer disk and etc.
3. exhibits high hardness up to 500-600hv, even 900-1000hv after heat treatment, strong wear resistance.
4. quick brightening, with the high deposition rate up to 10-18um/h.
open the cylinder: en-999a 50-70ml/l, en-999b 160-200ml/l.
consumption per square decimeter of workpiece deposited 10um coating thickness, need to add 8-10ml en-999a and equal en-999c.
