Finemac™ is an environmentally friendly, lead–free, free-cutting wire grade, which combines excellent machining properties with high hardness and good dimensional stability. This free-cutting high-carbon steel wire has been specially developed for high precision machined parts in fine-mechanical applications.
Switching from leaded steel to lead-free steel is a substitution in accordance with the ambitions of REACH, the EU regulation on chemicals and their safe use, which came into effect in 2007 and becomes mandatory in 2024.
Importantly, the material offers much shorter hardening times than other lead alloyed grades. As a result, users can obtain more efficient furnace utilization through shorter process times and benefit from lower energy costs per kilo produced.
Finemac™ has all the characteristics of a hardenable, free-cutting high-carbon steel such as 20AP, but with the important and additional benefit of being lead-free. It is ideally suited for producing long narrow components with tight tolerances. Finemac™ also has excellent cold-heading properties.
Positive customer feedback confirms that Finemac™ free-cutting wire is in terms of
now preferred to other carbon steel free-cutting wire.
