KOS21 Co., Ltd.
KOS21 Co., Ltd.

We have a good record in manufacturing sputtering targets and processing aerospace-related components.

We can manufacture sputtering targets in an integrated manner throughout all the processes from machining to bonding. We have a relationship with aerospace businesses whose requirements are difficult to achieve. We have a good record of processing different materials ranging from aluminum to difficult-to-cut materials (such as magnesium and Ti).

  • Business Outline

    Manufacturing of sputtering targets, precision machining , design and manufacturing of electrical instrumentation panels, general iron work, and maintenance

  • Product Strength

    With our thin wall cutting technologies, we can handle slicing magnesium alloy and aluminum alloy from blocks in 1 mm thickness (the materials regarded as difficult-to-cut). This cutting technique is used mainly for aerospace parts, which require precision and lightness. As for sputtering targets, we are the only company in Kansai with an integrated production system. We can handle cutting, machining, bonding, and vacuum packaging, once clients provide us with target materials. As for welding of metal materials, we have many technologies. In aluminum welding, in particular, we can handle TIG and MIG welding and electronic beam welding to targets, depending on customer needs. We have also established a bonding technology for different materials by utilizing the bonding technology between aluminum targets and back plates.
