Unverified个人DIY和维修优先选有铅Sn63/Pb37共晶锡丝，比无铅更易焊、假焊率低、烙铁温度可控制在300-350℃；但成品若需出口欧盟或商业销售必须用无铅（RoHS合规）86% similarUnverified含锡量越高（如无铅Sn99）焊点强度和导电性越好但熔点越高越难焊，Sn63/Pb37的63%含锡量是共晶最佳配比，性价比和焊接性能兼顾79% similarUnverified远红外高温机型内胆材质关键：优选304不锈钢内胆，镀锌板或喷漆内胆长期高温易生锈脱落，避免选用非不锈钢内胆的低温型高温柜76% similarUnverified刀片材质优先选304或316不锈钢，316耐腐蚀性更强适合频繁蒸煮高温环境；避免选普通铁质镀层刀片，长期接触酸性果泥易生锈75% similarUnverified选购恒温壶应看内胆材质：316不锈钢内胆优于304，防腐蚀性更强适合长期反复加热；玻璃内胆无金属析出风险但重且易碎74% similar
