Ecobrass is a term for brass alloys that contain less than 0.1% lead. Thus, they comply with current standards for use in contact with drinking water.

The alloy exhibits similar mechanical properties to other lead-containing brass grades. It is suitable for both casting and forming processes. Its notable properties include good machinability, corrosion resistance, resistance to stress corrosion cracking, polishability, and good hard and soft solderability.

These properties result from the significantly lower zinc content compared to Ms58 and the additions of silicon and phosphorus. This combination largely compensates for the absence of lead for machinability and the softer α-structure, compared to the harder α-β-structure of Ms58.

The silicon in the alloy leads to increased hardness and good machinability. The low phosphorus content deoxidizes the melt and makes it more fluid. Silicon and phosphorus also counteract zinc evaporation during melting. Nevertheless, the use of slag binders for copper alloys during the melting process is recommended.

Therefore, if it is important to produce lead-free castings or if you want to cold or hot form the casting later, this alloy is preferable to Ms58.

Composition: approx. 63% copper and 37% zinc
Edge lengths: 8-30mm
Thickness: 1mm
Lengths: 50-2000mm
Density: 8.44 g/cm³

This offer includes square tubes made of Ms63 CuZn37 (CW508L).

The length tolerances are up to +2mm, and for the edge dimensions +/-0.1mm.

For safer handling, we deburr all profiles before delivery. This goes beyond the common practice of delivering profiles with raw cut edges. If, for any reason, deburring is not desired, please let us know when placing your order.

Note:

For lengths over 1000 mm, significantly increased transport costs apply due to excess length. This means that 1500 mm and 2000 mm profiles are more expensive in the base price than 1000 mm profiles.
If you require quantities of more than 4 pieces for 1500 mm and 2000 mm, or more than 10 pieces for all other dimensions, we would be happy to provide you with a personal offer tailored to your specific needs.

Dimensions: 8-35mm
Thickness: 1-3mm
Lengths: 50-2000mm
Density: approx. 8.44 g/cm³

This offer includes brass U-profiles.
The length tolerance is up to +2mm, and the dimension tolerance is +/-0.1mm.

Please note that the products offered are semi-finished goods that are not specially surface-treated or polished. Due to dimensional tolerances, the wall thickness may be 1.1 mm instead of 1 mm. Under certain circumstances, precisely fitting profiles that also have a slight oversize could be difficult. For example, fitting a 6×6 mm square profile into an 8x8x1 mm U-profile may be challenging and require reducing the material thickness.

For safer handling, we deburr all profiles before delivery. This goes beyond the common practice of delivering profiles with raw cut edges. If, for any reason, deburring is not desired, please let us know when placing your order.

For lengths over 1000 mm, significantly increased transport costs apply due to excess length. This means that 1500 mm and 2000 mm profiles are more expensive in the base price than 1000 mm profiles.

Material: Ms58 CuZn39Pb3 (CW614N)

Ms58 is a common brass alloy with 39% zinc and up to 3% lead content. It is very suitable for casting and hot forming. The lead content has no effect on castability and ensures very good machinability of the solidified casting.
If the lead content in the alloy is a concern for you, you can also buy pure copper and pure zinc in convenient quantities in our shops to alloy lead-free brass yourself.
When casting zinc-containing alloys, it should be noted that zinc evaporates from the melt at temperatures above 907 °C. To prevent the zinc content from significantly decreasing, it should be quickly brought to casting temperature (950-1000°C) and poured.
The surface of the ingots is not polished and therefore somewhat duller. Nevertheless, the material is clean and free of impurities.
The molding sand available in our shops is very well suited as a molding material for brass casting.
