The characteristic of drill rod solder

(Of technology of solder of 1) drill rod heat temperature is lower, accordingly after drill rod solder of weldment be out of shape small, assure the measure precision of weldment simply. Together, the impact of the arrangement about weldment mother capable person and function is less also.
(Technology of solder of 2) drill rod applicably at all sorts of metals data, heterogeneous metal, metal and join metalloidly.
(3) can be over many spare partses or many drill rod solder of brazed seam, productivity is taller.
(4) can the spare parts with drill rod paper-thin or extremely delicate solder, and degree of finish, thickness differs very large part.
(The blemish of solder of 5) drill rod is: The surface when the heat-resisting ability of connect of drill rod solder compares intensity of poor, connect to compare solder of low, drill rod arranges the request that reachs weldment to install quality taller.

The use of drill rod solder
Use dimensions
Drill rod solder
Use at making component of careful appearance, electronic parts, heterogeneous metal and construction of mixed and disorderly thin plate, wait like construction of interlining component, beehive; Commonly used also at drill rod solder line of of all kinds different and hard alloy cutting tool

Hard drill steel expects (450 ℃ of ＞ of melting point of drill rod material) , be like cupreous radical, silver radical, aluminium radical, nickel radical to wait, have higher strength, can join the part that accepts load, use more extensive, be like frame of hard alloy cutting tool, bicycle.
Solder (450 ℃ of ＜ of melting point of drill rod material) , wait like stannum, lead, bismuth, solder intensity is low, principal use at soldering not to accept load but the weldment with request good sealing, wait like container, outside component. Drill rod solder is principal get be used extensively in the making course of study such as mechanical, electric machinery, outside, radio.
