SOLDER Chemical Properties,Uses,Production
Definition
solder: An alloy used to join metalsurfaces. A soft solder melts at a temperaturein the range 200–300°C andconsists of a tin–lead alloy. The tincontent varies between 80% for thelower end of the melting range and31% for the higher end. Hard solderscontain substantial quantities of silverin the alloy. Brazing solders areusually alloys of copper and zinc,which melt at over 800°C.
Definition
An alloy used in joining metals. The molten solder wets the surfaces to be joined, without melting them, and solidifies on cooling to form a hard joint. The surfaces must be clean and free of oxide and a flux is often used to achieve this. Soft solders consist of lead with up to 60% tin and melt in the range 183–250°C. Soft-soldering is used, for example, in plumbing and making electrical contacts. Brazing solders are copper–zinc alloys that have higher melting points and produce stronger joints than soft solders; silver can be added to produce silver solders.
Definition
A low-melting alloy usually of the lead-tin type used for joining metals at temperatures below 425C. The solder acts as an adhesive and does not form an intermetallic solution with the metals being joined.
