According to the products outer surface is polishing processing, tungsten rod can be divided into unground tungsten rod and polished tungsten rod.
Polished tungsten rod by polishing processing, through the unground tungsten rod is processed into polishing tungsten rod, tungsten rod surface that becomes more bright. Due to the pure tungsten high hardness, abrasion resistance, corrosion resistance, high brittleness, can use physical polishing, electrolytic polishing method for processing the surface of the product.
Physical polishing refers to the use of the physical properties of the outer surface of the round bar grinding tungsten frosted type.
Obtained using electrolytic resulting polishing tungsten rod surface bright, smooth, and through the electrolytic polishing tungsten rod surface corrosion resistance is very good.
