Tungsten has a high density, which makes it convenient for ionizing radiation shielding. Despite the higher density compared to traditional and cheaper lead, tungsten shielding is less heavy with equal shielding properties, and more effective if the weight is the same. Tungsten is a very refractory and hard metal, which makes it difficult to process. Therefore, more ductile tungsten alloys with nickel, iron, copper, etc. are used. Cr 16.0%-18.0% We buy alloys of the following grades: VN/VNZh alloys (category: Tungsten 12) (W - 80 - 90% Ni - 5 - 10% Fe - 1- 3%) VD alloys (W - 70 - 80% Cu - 20 - 30%)

"In this method, a process on the surface of zinc, zinc-iron or zinc-nickel produces a defined thin and durable passivation coating, which enhances corrosion resistance. The different passivation processes differ with regard to corrosion protection, appearance, coating thickness and colouring. Often the passivation processes are additionally enhanced by seals (topcoats). These topcoats not only provide even greater corrosion protection, but also provide a more uniform appearance. The topcoats are adjustable to define the friction properties. Passivation processes are provided exclusively chrome-6 free."
