Mechanics resistance and ductility

Brass is basically an alloy of copper and zinc with a special combination of properties. Brass keeps deformability thanks to its component copper, but with a higher resistance due to zinc. Few materials add properties such as mechanics resistance and ductility, with its excellent resistance to corrosion and unequal plasticity.

Ideal material for its use at accessories transporting water

The excellent resistance of brass to corrosion and extreme temperatures, its environmental respect being recyclable 100% and its capacity of inhibit microorganisms.

Production standards

The brass used at rmmcia is fulfilling all standards regulated by national laws within European Union, as for instance:

For manufacturing our brass accessories we use brass of certified quality as per following regulations:

  • For hot forging: brass UNE-EN 12165 CW617N.
  • For bar machined parts: brass UNE-EN 12164 CW614N.
  • For mould castings: brass UNE-EN1982 CB753S.
  • Fulfilment of regulation UNE-EN149101

    Fulfilment of regulation UNE-EN149101 – Anexo A of composition of metallic materials in contact with water for human consumption, that for Lead content establishes a maximal limit of 3,5%

  • DIN 50930-6

    Forging materials, Lead content under 2,2% as per DIN 50930-6 and D.M 174 of 06/04/2004.

  • Agreements ACS

    Being the brass fittings entirely metallic they automatically benefit of agreements ACS (Attestation Conformité Sanitaire), following Order of 29th May of 1997 completing Decree 89-3 of January 3rd 1989 in referral to materials used in human consumption’s water distribution installations.
