ALL THESE MATERIALS SATISFY THE RECENT EUROPEAN AND AMERICAN REGULATIONS ON THE TRANSFORMATION/TREATMENT OF WATER FOR HUMAN USE.

BRASS

Metal alloy based on copper and zinc, with a prevalence of copper, to which are added, sometimes, various quantities of other
elements such as manganese, iron, aluminum, tin, which improve its mechanical properties and resistance to agents weather. It is
used for its hardness and corrosion resistance.

CW614N

High machinability and hot plastic deformability

Although it is the standard alloy for stamping it also presents excellent machinability for chip removal. The low lead content, lower
thant 2.2%, means that it can be used for contact with drinking water. It is included in the 4MS “Positive List” and can be used for
up to 10% of the surface of the domestic supply of water for human consumption.

CW617N

Standard alloy with high machinability for chip removal

Alloy specifically created for round section bars, it is recommended for turning parts and has excellent workability performance for
chip removal. Optimization of the chemical composition guarantees reduced chip size and optimal mechanical characteristics. Find
application in taps, accessories, clamps and components in general.

CW511L

Standard antidezincification alloy for the USA market

Standard dezincification resistant alloy which thanks to its reduced lead content has applications in the United States market. The
modest lead release makes it suitable for use in contact with drinking water; in fact it is among the 4MS approved alloys and is
included in the “Positive List”.

CW510L

Alloy with low lead content and optimised machinability

Its lead content below 0.2% allows the use in the USA market for which it is NSF372 certified. Its good machinability for chip
removal makes LFB the standard alloy among low lead content materials. It is included in the 4MS “Positive list” it is used for parts
that come in contact with drinking water.

CW610N

Leaded Muntz Metal for mechanical machining

Named “Leaded Muntz Metal” it presents fair tool machinability and good hot formability. Thanks to its excellent mechanical
characteristics and its copper content it is used for the production of parts used in heat exchangers.

CW625N-CW626N

Standard anti dezincification alloy

Optimised for mechanical machining for chip removal it has low lead transfer values. It therefore has applications in taps and
components in contact with water for human consumption as a substitute for the alloy CW602N. It is approved by 4MS and is
included in the “Positive List” of metallic materials that can be used in contact with drinking water.

CW724R

Alloy lead-free

Wieland recognised the potential of environmentally friendly, lead free machining brass at a very early date, and adopted the
pioneering role in Europe by developing ECOBRASS. This proved to be a farsighted course into the future. Today, ECOBRASS is
marketed worldwide over a cooperation network and available, even in smaller quantities, from trade partners. We also market
this material under the name “CUPHIN” for sanitary products

BRONZE

This alloy mainly composed of copper (Cu), is enriched with tin (Sn) up to 8-9%, giving rise to alloys with goodmechanical characteristics and great resistance to corrosion.

Aloys used: CuSn5Zn5Pb2 – CuSn4Zn6Pb3
