ALPACA

High Nickel Brass

High-nickel brass is deceptively similar to silver, although chemically it has nothing to do with it. So it is called new silver or Chinese silver, but yet another common name is alpaca. It is a sought-after raw material for creating jewelery.

Our high-nickel brass sheets and strips are made of a copper alloy with a high admixture of nickel and zinc. High-nickel brass has a different color than traditional brass due to its high nickel content. Alpaca, due to its resemblance to silver and great properties (it does not darken, does not irritate the skin), is more and more willingly used to make jewelry.

MANY APPLICATIONS

Advantages of high-nickel brass

Other advantages of high-nickel brass make it widely used in the production of electrical components, in precision mechanics or the production of artistic products. Alpaca is commonly used in the production of high-quality tableware and tableware, precision medical equipment, or musical instruments such as saxophones and transverse flutes. Often, items made of high-nickel brass compete with items made of, for example, brass, bronze or copper.

VARIOUS KINDS OF

Alpaca in European Standards

We offer various types of alpaca, which we produce in accordance with Polish and European standards, e.g. MZN12 (CuNi12Zn24), MZN15 (CuNi18Zn20) and MZN 18 (CuNi18Zn27) alloys. Our high-nickel brass is resistant to corrosion, shows high elasticity and has high resistance to abrasion.

We produce high-nickel brass strips with a thickness of 0.1 mm to 2 mm and a width of 5 mm to 360 mm. Our alpaca strips and sheets have the following dimensions: thickness from 0.2 mm to 5 mm, width up to 360 mm and length up to 2000 mm. The details of the dimensions are specified in detail by our specialists for each order. Please do not hesitate to contact us.
