"The alkaline zinc-iron alloy coating is very commonly applied to steel and ferrous materials. It has been used successfully for many years in the automotive and electrical industries, in equipment and mechanical engineering and also in sheet metal processing. It is characterised by a higher resistance to environmental influences. In addition to the classic galvanising process, the zinc-iron process provides a high degree of corrosion protection paired with an attractive surface design (black, silver), as well as uniform coating thickness distribution. This is a crucial advantage for workpieces with fit sizes. This process is suitable for both barrel and rack goods."

Self-tapping threaded inserts for making high-strength, wear-free, vibration resistant screw connections in materials with low shear strength such as aluminium and aluminium alloys, brass, bronze, cast iron, duro and thermoplastics. The threaded inserts are tapered at the bottom and have a cutting slot. By screwing in they cut their own threads inside a receiver hole. This guarantees a completely secure and firm anchoring in the host material. Internal thread D1 acc. to ISO 6H. The threaded inserts with cutting slot spring slightly inwards in the slot region in some materials. This results in a screw locking effect. If this is not desired, we recommend the threaded inserts with a cutting bore.

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%)
