Product Description Tungsten alloys are ideal replacements for traditional lead sinkers. The tungsten alloys are sinking fast, strong-wind resistant and environmentally friendly in agreement with the international environmental protection standard. Elastic tungsten is one of our latest developments. For hard tungsten alloys, we have more than 20 reference models with varied sizes: Water droplet, bullet, round in charge offing, ball, and diamond, et. Al. We provide customer-centered service. Customers give us their design in details or in raw drafts. Our experienced R&D engineers will develop the precise 3-D structure, module and manufacture. Down stream processes are available upon customer request, such as soldering, polishing, galvanic coating (gold, silver, copper, nickel, black nickel), and painting in various colors.
