H62 H65 Solid Pure Small Copper Balls For Valves 1/2 Inch 12.7mm Light Weight

Brass has better toughness, and beryllium copper and copper are inferior in elasticity and toughness.
Phosphorus copper anode ball is an excellent electroplating material,

mainly used in printed circuit (PCB) and hardware, decoration industry.
With the rapid development of electronic technology, the demand for production of various circuit boards has greatly increased.

The demand for copper as an important raw material for electroplating anodes is greatly increased,

and PCB precision PCBs require phosphor bronze balls as anodes.

Phosphor bronze ball is suitable for electronic circuit board, especially high-precision multi-layer circuit board,

an essential component of this electronic product.

It relies on high quality PCB phosphor bronze ball anode as the basic raw material for manufacturing circuit board.

Therefore, the demand for phosphor bronze anode balls is considerable.
High-quality phosphor bronze anode balls are different from other important indicators of copper alloys:
1. Purity-The best raw material for the manufacture of phosphor bronze anodes is cathode electrolytic copper.

The raw material used is Cath 1# with the best quality in cathode electrolytic copper, and the purity is 4 9 or more.
2. Phosphorus content - The optimal range of phosphorus content is 0.04~0.065%,

and the phosphorus content is controlled at 0.05% or more,

while the phosphorus content of most other producers is close to or less than 0.04%,

in order to save costs, the lack of phosphorus will Lead to more anode slime,

anode bag cleaning frequently (more than once a month),

a large number of anode mud will affect the role of brightener to

make the coating rough, increasing the scrap rate of the finished product.
3. regular fine grain structure - the use of kneading method to produce phosphorus copper anode,

when about 0.05% of the phosphorus is evenly distributed in the copper grain,

so that the black film on the surface of the phosphorus copper anode is even, the copper dissolved into the plating solution
