Characteristics
Aluminum-Brass
(Cu+Zn+Al)

JIS H 3300 JIS H 3300 ASTM B111(M) ASME SB111(M) EN, BS, DIN etc

C 6870 T C 6872 T C 68700 C 68700 ※Due to each Standard

Improved Dezincfication Corrosion Resistance and corrosion resistance compare to normal Brass(Cu+Zn). This alloy is widly used instead of Admiralty for Plant which uses seawater.

Admiralty-Brass
(Cu+Zn+Sn)

JIS H 3300 ASTM B111(M) ASME SB111(M) EN, BS, DIN etc

C 4430 T C 44300 C 44300 ※Due to each Standard

Improved Dezincfication Corrosion Resistance and corrosion resistance compare to normal Brass(Cu+Zn). This alloy is used for Plant which uses plain water, as errosion/corrsion resistance for seawater is not enough.

90/10 Copper-nickel
(Cu+Ni+Fe+Mn)

JIS H 3300 ASTM B111(M) ASME SB111(M) EN, BS, DIN etc

C 7060 T C 70600 C 70600 ※Due to each Standard

This alloy is used for heat exchanger which uses seawater. Nickel-content enhances corrosion resistance and alkali-resistance of alloy. Errosion resistance for seawater of this alloy is better than Aluminum-Brass.

70/30 Copper-nickel
(Cu+Ni+Fe+Mn)

JIS H 3300 JIS H 3300 ASTM B111(M) ASME SB111(M) EN, BS, DIN etc

C 7150 T C 7164 T C 71500 C 71500 ※Due to each Standard

This alloy more enhances the corrosion resitance and high temperature strength than 90/10 Copper-nickel, and has hihg ammonia-resistance. Increased iron and manganese in the component of this alloy is known as Yoko-ron(C71640), and it has good resistance at high temperature environment.
