BBIEN supply Tin lead series powder of  type3 Sn63Pb37 and Sn62Pb36Ag2 Pb series solder powder 25~45micron.

1.The welding 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.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.

4.Advanced powder classification and collection technology enables Type 2-Type 3 alloy welding powder free of powder smaller than 20um.
