Spot welding electrode Alrode®

resistance weldingfor aluminumfor copper

For over 50 years, Lebronze alloys has been an international reference in the Automotive industry for resistance welding products. Being a major partner to almost all car builders involves important responsibilities: not only manufacturing high-quality alloys and electrodes but also being a pioneer in innovation. This allied with a Research & Development program launched in partnership with specific automotive manufacturers led to the setup of a dedicated and exclusive patented manufacturing process for the electrodes. Alrode® is one of the key successes of this program. Our revolutionary electrodes for aluminium sheet resistance welding, Alrode® Alrode® is a premium quality solution that meets the stringent requirements of aluminium sheets resistance welding. Alrode® is a wrought, age hardening CuCrZr (C18147) alloy with very high purity that performs well above the market properties for standard electrodes’. It has a fully integrated patented manufacturing process with automated control certified ISO 9001 / AS/EN 9100. Since Alrode® is a low-alloy copper, it has excellent electrical conductivity. Thanks to the addition of small quantities of chromium and zirconium, it also exhibits very good mechanical properties such as very high hardness. Alrode® has an excellent resistance to corrosion and softening which guarantees a long service life. Alrode® also optimises your total cost ownership (TCO): requires fewer electrode changes thus reducing consumption and less line stoppage. less straightening improved weld spot quality
