OF BRASS

Lots of advantages

Our brass strips and brass sheets are made of various types of brass, depending on the proportions of the metals they contain. Brass is dominated by copper, which can be melted with zinc, lead, silicon, chromium, manganese or iron.

Brass sheets and strips are widely used for their advantages: corrosion resistance, ease of forming, ductility, strength and durability. Brass is suitable for casting and cold working. It is used to manufacture, for example, home fittings, building fittings, musical instruments, padlocks, and ship screws. Brass is often used by artists in metalwork.

POLISH AND EUROPEAN

Brass alloy standards

In our company, we produce brass sheets and brass strips from various types of brass alloys manufactured in accordance with Polish and European standards. We offer, among others:

  1. two-component brass – e.g. M90 (CuZn10), M85 (CuZn15), M80 (CuZn20), M70 (CuZn30), M60 (CuZn40), M67 (CuZn33), M63 (CuZn37),
  2. lead brass – e.g. MO64 (CuZn34Pb3), MO62 (CuZn36Pb1.5), MO61 (CuZn36Pb3), MO59 (CuZn39Pb2) MO58A (CuZn39Pb2), MO58b (CuZn40Pb2), MO58 (CuZn40Pb2),
  3. high nickel brass.

We produce brass strips with a thickness of 0.1 mm to 3 mm and a width of 5 mm to 360 mm. Our brass strips and sheets, on the other hand, have the following dimensions: thickness 0.3 mm to 100 mm, width from 360 mm to 1000 mm, length up to 2000 mm. It is possible to produce brass sheets in other dimensions, but it requires direct contact with our specialists and arranging details.

Brass is an alloy of copper with zinc, the latter being a maximum of 40%. In addition, it may contain additives of other metals: tin, lead, silicon, aluminum, chromium, manganese or iron. Brass is orange-yellow (sometimes close to gold), and with smaller amounts of zinc it even turns copper. It melts at a temperature below 1000 degrees Celsius.

The use of brass is very wide and includes, among others industries such as construction, electrotechnical, machinery, shipbuilding, automotive, metalwork and chemical. This alloy produces:

  • fittings,

  • ammunition,

  • construction fittings,

  • machine parts,

  • musical instruments,

  • cups and medals,

  • coins,

  • monuments,

  • bells,

  • padlocks,

  • marine propellers,

  • picture frames and mirrors.

In our company, we deal with the production of brass sheets and brass strips.

Brass is eagerly used due to its undeniable advantages, which include corrosion resistance, ease of forming, ductility, strength and durability (due to the zinc content in the composition – then this type is used to make jewelry). Suitable for casting and cold forming.

Due to its composition, brass is divided into:

  1. Two-component brass – e.g. M95 (CuZn5), M85 (CuZn15), M75 (CuZn25), M70 (CuZn30), M60 (CuZn40).
  2. Lead brass – e.g. MO64 (CuZn34Pb3), MO62 (CuZn36Pb1.5), MO61 (CuZn36Pb3), MO58A (CuZn39Pb2), MO58b (CuZn40Pb2), MO58 (CuZn40Pb2).
  3. Special brass – also divided into:

  • aluminum brass – MA77 (CuZn20Al2), MA59 (CuZn36Al3Ni2),

  • tin brass – MC90 (CuZn10Sn), MC70 (CuZn28Sn), MC62 (CuZn38Sn),

  • manganese brasses – MM59 (CuZn40Mn), MM57 (CuZn40FeMnSnAl), MM56 (CuZn40Mn3Al),

  • high-nickel brass – MZN18 (CuNi18Zn27), MZN15 (CuNi15Zn21), MZN12 (CuNi12Zn24),

  • nickel brass – MN65 (CuZn29Ni6),

  • silicon brass – MK80 (CuZn16Si3).

We also invite you to familiarize yourself with our offer of copper strips and sheets.
