Use
C2700
(65:35 brass)
Cold-work-related rolling characteristics are good and the strength is high and I bend it and turn for complicated processing product, deep drawing processing by processing as a spirit, the shallow diaphragm nature is good.
Electric appliance material, household articles, communication machine, precision instrument parts
C2800
(brass for the bending)
In muntsumetaru, I am suitable for bending to cold intervals between the heat.
Wiring appliance, nameplate, apparatus parts,
C3602
(one kind of excellent cut brass)
With moderate ductility, I am used for a high-speed automatic lathe and, also, am suitable for processing between the heat.
Bend valve, parts of the machine
C3604
(two kinds of excellent cut brass)
It is the brass that cutting characteristics were largely improved by adding lead.
I am used for a super-high-speed automatic machine, and the tool life gets longer than one kind.
Parts, gear, valves such as the precision instrument or clock
C3771
(brass for forging)
I am used for a forging and pressure mark between the heat.
High pressure valve, the parts that a high mechanical property is required, rotor bar
C4641
(nebaru brass)
The hardness, the strength increase by tin, but on the other hand they decrease the growth. In addition, I am superior in corrosion resistance for the seawater.
Parts for the ship
C6782
(high power brass)
The feature is that-related gadeki, corrosion resistance to pitch a camp by some manganese and aluminum being included are strong.
Forging, ship between the heat, parts for the mine
C3604 kadomiresu RoHS correspondence
(two kinds of excellent cut brass)
C3604CdL (kadomiresu) is the product which regulated cadmium by RoHS order. The kadomiresu content guarantees 75 ppm or less with standard materials in the company, and, as for the characteristic of materials, as for the conventional brass stick and difference, there are none.

Characteristic
KS-B (heteromorphic brass)
I am used for a general shape and straight angle mainly.
KS-H (hollow brass)
I am used for a complicated shape with the materials which I developed for emptinesses.
KS-R (heteromorphic brass for building materials)
I make the extruded nature better and am suitable for a sharp, complicated shape.
