The brass fibers are a copper and zinc alloy containing a minimum of 60% of Cu and are lead-free. The fine brass fibers are of low bulk density and are completely oil-free.
Microstructure of brass have a big influence on the thermal conductivity. The mainly alpha structure of this brass and the absence of any impurity, boost the thermal conductivity up to 130W/m*K
| Specific gravity | Nominal diameter | Bulk density | |
| Brass Fiber | 8,40 g/cm3 | 0,20 – 0,30 mm | 20 – 30 mL/100 g |
