应用范围/Introduction

含有少量铁、硅、锰的黄铜焊丝。熔融金属流动性好，由于硅的存在，更加有效的抑制了锌的蒸发。可用于铜，钢，铜镍合金，灰口铸铁的熔化极气体保护氩弧焊，以及镶嵌硬质合金刀具。焊前需经400-500℃预热。

This braze welding rod are similar to RBCuZn-A rods but contain additions of iron and manganese which serve to increase the hardness and strength. In addition, a small amount of silicon serves to control the vaporization of the zinc, yielding the “low-fuming” property. The nickel addition assures uniform distribution of the iron in the deposit.
