KS series
Original development alloy
Alloy number | Characteristic |
KS-B (heteromorphic brass) | It is often used for a straight angle and a general variant, and the nature extruded for a characteristic than C3604 is good, and it is in the materials that pushing out can do a high product of the precision in pushing out between the heat. The name is often used in hinges (hinge) and comes from B of the butterfly. |
KS-H (hollow brass) | It is the alloy which was developed to produce hollow materials. It is in the shapes near the air such as pole materials and the materials which can cope with the high product of the degree of difficulty more as well as hollow materials for a characteristic. As the name is used for Jolo (hollow) materials, I come from H of Jolo. |
KS-R (heteromorphic brass for building materials) | It is often used for decoration hardware and angle brace, and it is in the materials which further from KS-B make the extruded nature better for a characteristic, and can cope with a sharp shape. I become a factor that the color becomes the color that is almost gold than C3604 and is used for accessories. The name is often used for rail materials and comes from R of the rail. |
