The company Avec Glob sells at various prices from manufacturers a variety of rolled products — pipe, sheet, tape, which are made of copper-nickel alloy Melkhior brand MN19. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Composition and application

Melchior MN19, produced in accordance with GOST 492−2006, is a copper alloy with nickel and zinc, additionally doped with brass, which gives the material

yellowish brown color. To improve the casting properties of the metal, the alloy also contains a limited amount of lead and tin.

Typical areas of use of the alloy is the production of various decorative objects and jewelry (jewelry). In industrial practice, nickel-grade MH 19 is used for the production of wind musical instruments, valves, components of precision optical equipment and instruments, fittings for the food and dairy industry, as well as consumer accessories (zippers) and fasteners — screws and rivets.

The alloy MN19 is distinguished by its high corrosion resistance and good workability, and therefore it is often produced parts of medical equipment and tools.

The chemical composition of the alloy MN19, which meets the technical requirements of the standard, is presented in the table (numerical data — in percent, copper — base):
