Aluminum Alloy Copper Lead Free

BAR 2007 LF

Available formats: Bars

Typical applications and uses:

It has excellent machining behavior, with high cutting speeds and good chip shedding, so its field of use is very varied.

 

It has relatively little resistance to atmospheric corrosion, so a protective anodizing is recommended.

 

EN AW-2007 is a copper alloy to be gradually replaced due to its lead content and can be replaced by 2007 LF alloy or EN AW-2011 or EN AW-2017).

Features:

For a few years, the European Community has been working to reduce the content of substances dangerous to health and the environment, which is why at Broncesval we have introduced 2007 LF (Lead Free / Lead Free) aluminum bars

 

The latest RoHS directive (2018/740 / EU) and REACH set the limit for lead (Pb) in aluminum alloy to 0.1% as of 05/18/2021 (previously it was 0.4%). At Broncesval we have alloys such as 2007 LF where LF stands for Lead Free or Lead Free.
