合金刀头用什么焊接更好?
都是用铜焊,强度不是太高,如果需要更好的焊接效果,可以考虑用MG130 ,流动性好,易操作,强度高,要高一倍呢.达到7000psi(483MPa)
MG130
\x05Super strength,general use brazing rod.
\x05Excellent for over laying and build-up at low temperatures(760~780℃).
\x05Excellent for close fitting joints,thin-flowing at high temperatures (900~955℃).
\x05Designed to build-up or join carbon steels,alloy steels,cadt iron,and many non-ferrous materials.
\x05For uses such as:
-gear teeth build-up -attaching carbide cutting tips
-bulid-up of bearing shafts -joining bicycle assemblies
-brazing of rusty surfaces -heavy equipment repair

Classifications
Similar to:
AWS/SFA A5.8…………………………………………………………….RB CuZn-D
DIN 8513………………………………………………………………L-CuNi10Zn 42
For best results,use a neutral flame.
Hints
\x05Rough-grind surfaces prior to brazing.
\x05Use neutral flame concentrated on the base metal,not on the alloy.
\x05To prevent overheating,keep torch in constant motion.
\x05Additional passes can be made without removing flux residue from previous passes.Allow part to cool slowly.
\x05Excellent for losing gaps or building-up worn areas such as bearing seats,chipped gear teeth,etc.
