Features of product

1)The soldering powder is ball shaped,the dark part is a tin rich area and the light part is a lead rich area.The pictures show the good sphericity,homogenous alloy composition and smooth surface of the product. 

2)Even particle size distribution

Particle size classification and final typing technology enables stable particle size of the product provided to customers.

3)Low oxygen content:

Oxygen content is strictly controlled during production and packing of allalloy welding powder.Leco oxygen determinator is adopted to determine the surface oxygen content and chemical assay is adopted to determine the total oxygen content.
