Before you upload your CAD file, you likely have granular engineering or supply chain concerns. We don’t hide behind sales reps. Below are direct, technical answers regarding heavy-plate laser dross, transit oxidation, and RoHS compliance.
Can you laser cut 6.0mm thick brass without severe edge burrs or dross?
Yes. Standard CO2 lasers struggle with 6mm brass due to extreme heat reflectivity, which leaves heavy dross (melted slag) on the bottom edge. We solve this by using high-wattage Fiber Lasers paired with high-pressure Nitrogen (N2) assist gas. The fiber laser easily penetrates the reflective surface, while the N2 gas instantly evacuates molten material and cools the cut-zone. The result is a clean, dross-free edge that rarely requires secondary mechanical deburring.
Brass scratches easily and oxidizes. How do you protect cosmetic parts during transit?
A dimensionally perfect part is useless if it arrives scratched or tarnished. We do not use loose bulk-bin packaging for cosmetic brass. Flat surfaces are protected with low-tack peel-off films. Components are then nested in custom die-cut polyurethane foam so they never touch each other. Finally, the entire batch is vacuum-sealed with active desiccants to completely block atmospheric moisture and prevent transit oxidation (the green patina).
Our end-product must be sold in Europe. Do you provide RoHS-compliant, lead-free brass?
Absolutely. While traditional free-machining brass (like C36000) utilizes Lead (Pb) for chip control, it violates RoHS/REACH directives. We stock and machine strictly compliant lead-free alternatives, such as Eco-Brass, low-lead Bismuth alloys, and pure C27400/C28000. Simply specify “RoHS” on your RFQ, and we will include the certifying Protokoly o zkouškách materiálu (MTR) confirming the alloy chemistry with your shipment.
