Lead free aluminium bars

lead free alloy 2033

The 2033 Lead-Free alloy has many potential applications; it is highly machinable due to its fine chip formation, high mechanical properties and comparatively better anodizing and soldering capabilities than other alloys such as 2011, 2007 or 2030.


Alloy 2033 Lead-Free is the alternative to alloys 2011, 2007 or 2030.


It is a tin-free alloy, which avoids the fragility that this element brings to the material and also the weakening or breakage of machined parts when subjected to fatigue or extreme temperatures (< -13ºC or > 160ºC).


Its main applications are in the following sectors: automotive, electrical and electronic industry, precision machining, defence, forging, screws, nuts, threaded parts…
