Zusammenfassung: | The utility model belongs to a cutting-tool, and in particular relates to a brazing alloy rust scraper. The prior traditional rust scrapers are made of carbon steel blades which are easy to get heated, dull and easy to slip. When in operation, the blades is needed to be replaced, which is time-and-labor-cost while with a bad rust removing effect. The utility model aims at overcoming the shortages and has a dual-homalocephalus and duplex ally, which is made after striking and forging the two ends of the round steel into the flat head and welding the two alloy blades at the ends of the two flat heads together with copper. The utility model has the advantages of rational structure, convenient carrying, time and labor saving and excellent rust removing effect. |
