EN1A Pb Bright Bar Manufacturer & Supplier
EN1A with 0.15-0.35% lead added. The lead acts as an internal lubricant at the tool tip, lifting cutting speed by roughly 25% and extending tool life on long automatic turning runs. Lead-bearing steel — confirm RoHS or ELV restrictions before specifying for automotive or electrical assemblies destined for the EU.
