What is medium phosphorus chemical nickel generally used for?

The advantages of electroless nickel plating are:

1. The coating is uniform, and any irregular shape, deep hole and groove can obtain the same thickness.

2. The coating has excellent adhesion, few pinholes, excellent luster and natural lubricity.

3. The coating has high hardness and wear resistance (hardness is close to hard chromium after heat treatment)

4. The coating is resistant to corrosion by alkali, hydrochloric acid and organic solvents.

5. The coating has good conductivity: 60- 120 ohm/cm.

6. It can improve the defects of easy peeling and cracking of hard chromium electroplating.

Phosphorus-containing electroless nickel plating has a wide range of applications, as listed below:

1. Communication industry: satellite communication, wireless communication, 3 C products, etc.

2. Mould industry: industrial moulds for plastics, rubber, glass and ceramics can replace hard chromium.

3. Textile industry: yarn guide hook, power needle, yarn lifting tube, etc.

Precision instruments: cameras, clock parts, gears, probes, mechanical parts, etc.

5. electronics industry: PCB, disk drive, electroless gold plating bottom layer,

List machine, fax machine shaft, etc.

6. Chemical industry: ultra-hard drilling nozzle pump, reaction tank conveying pipe, gas switch, etc.

7. Automobile industry: electric valves, piston bearings, valve shock absorbers, drive discs, etc.
