广西柳州市合金材料厂继试成铬锆铜电极合金和航空DJ—100电极合金材料之后,近期又研制成功焊铝用的HDLC电极合金材料。并于1986年5月通过技术鉴定。 HDLC电极合金是焊铝用高导电率的铜合金材料(导电率>85％IACS,硬度HRB≥65,软化温度≥550℃)。其性能指标超过国际标准ISO5182—1978(E)中规定用手焊铝合金的镉铜合金性能指标。经使用验证,HDLC电极合金材料的使用寿命比镉铜电极合金材料高三倍以上,焊接质量比镉铜电极合金材料好,故前者可取代后者。HDLC电极合金材料可广泛应用于航空、化工、电子和机械等部门焊接铝及铝合金。
Liuzhou City, Guangxi alloy materials plant after the test into chromium-zirconium-copper electrode alloy and aviation DJ-100 electrode alloy material, the recent development of a successful welding HDLC electrode alloy material. And in May 1986 passed the technical appraisal. HDLC electrode alloy is a high conductivity copper alloy with aluminum welding (conductivity> 85% IACS, hardness HRB ≥ 65, softening temperature ≥ 550 ℃). Its performance index exceeds the international standard ISO5182-1978 (E) in the hand-welded aluminum alloy of cadmium copper alloy performance index. After the use of verification, HDLC electrode alloy material life than the copper and copper electrode alloy material more than three times higher than the welding quality of cadmium and copper electrode alloy material, so the former can replace the latter. HDLC electrode alloy material can be widely used in aviation, chemical, electronics and mechanical welding aluminum and aluminum and other departments.
