.Process features: , Aluminum alloy alkaline electroless nickel is an electroless nickel that is particularly suitable for aluminum and aluminum alloy pre-plating
b. Reduce contamination of subsequent acidic electroless plating or other electroplating solutions
, Excellent bonding force
/>, the processing of complex workpieces shows its superiority
, can also be used for the electroplating base layer of other substrates
, low operating temperature
Instructions for use
Aluminum alloy alkaline pretreatment Nickel plating uses the internationally accepted three solutions, B and B. Open the cylinder with B and analyze the consumed components of the replenishing working fluid according to the nickel ion concentration. Replenish with, it is extremely convenient:

3. Prepare the solution:
When opening the cylinder, add the prepared solution/water into the tank.
Add the added B and B, stir evenly mechanically, and filter with a filter.
Add pure water to approximate required volume.
Use ammonia water to adjust the value to . (approximately ml), add water to the scale, and then plating according to process requirements.
