SK Metal was established in February 2012 under the direct management of Sunkwang AMPA. The company manufactures products such as special aluminum welding materials, silver-alloy welding materials, silver-alloy powder welding materials and powder welding materials for accessories, and flux. In particular, the special aluminum welding materials do not contain flux, making it possible to do the welding works only by using them. These have the specific property that allows the welding of "aluminum and aluminum", and "copper and aluminum", and " copper and brass" to take place at about 450?C. Theses special aluminum products are used for the welding of air-conditioners and automobiles (condenser, evaporator, heat-core).The silver-alloy welding materials can be largely divided into BCuP welding materials and BAg weldingmaterials. When it comes to products&＃39; quality, the surfaces of billets are kept clean due to the use ofhigh-frequency induction furnaces and the analysis and checking of quality through smeltingfurnaces are conducted each time, surely making people exclaim "Something different in theSunkwang AMPA&＃39;s products" while using them. As the other products of the company are alsoreadily inspected with its own analysis tools before being supplied, they will be in the best conditionswhen they are used by our customers.
