微晶铜基钎焊合金焊片国际分类号:B23K35/28,35/40 C22C 9/02;申请号:85105171;申请日:85.7.8:申请人:天津市冶金局材料研究所该焊片是用液态急冷技术(单辊法或双辊法)制做的,可以制成细丝或薄片。这种无银焊片的特点是钎焊温度低、流动性能好、填充能力强,具有良好的综合机械性能,焊缝耐冲击,抗弯、导热、导电及耐蚀性能均良好,适用于低压电器,仪器仪表,热交换器,散热器等部件的钎焊,完全可以代替银基合金焊片。
Microcrystalline copper-based brazing alloy welding lugs Application Number: 85105171; filing date: 85.7.8 Applicant: Institute of Materials, Tianjin Metallurgical Bureau The solder lugs Is the use of liquid quenching technology (single roll method or double roll method) made, can be made into filaments or sheets. This non-silver solder is characterized by low brazing temperature, good flow properties, strong filling ability, good comprehensive mechanical properties, good impact resistance, flexural resistance, thermal conductivity, electrical conductivity and corrosion resistance. It is suitable for low pressure Electrical appliances, instrumentation, heat exchangers, radiators and other components of the brazing, can replace silver-alloy welding.
