STEELMAX Metal Story

Bronze Casting (청동)은
주석청동, 인청동, 연청동을 포함합니다.

주물로 만들기 쉽고,
주물표면이 아름다우며,

내압성, 내마모성, 내식성이
우수한 특징을 가지는 금속입니다.

Bronze Casting CAC401C 는 피삭성이 좋고 납땜성 (Brazing) 및 Soldering성이 좋습니다.
수도꼭지 부품, 베어링, 명판, 일반기계부품등으로 사용되며

Good in machinability and also good in brazing
and soldering properties.

Use for water tap parts, bearing, identification plate,
general machine parts etc.

Bronze Casting CAC402C 는 내압성, 내마모성, 내식성이 좋고,
기계적 성질도 좋습니다, 또한 납 용출량이 적습니다.

베어링, 슬리브, 부싱, 기어, 선박용 원형창
전동기기 부품으로 사용됩니다.

Good in pressure tightness, abrasion resistance and corrosion resistance and,
moreover, good in mechanical properties. Very little lead leaching.

Use for bearing, sleeve, bushing, gear, side scuttle for ship,
motor-driven instrument part, etc.

Bronze Casting CAC403C 는 내압성, 내마모성, 기계적 성질이 좋고,
내식성에서 CAC406C보다 좋고, 납 용출량이 매우 적습니다.

베어링, 슬리브, 부싱, 밸브, 기어,
전동기 부품, 일반기계부품등으로 사용됩니다.

Good in pressure tightness, abrasion resistance and mechanical properties,
and better in corrosion resistance than C402C. Very little lead leaching.

Use for bearing, sleeve, bushing, valve, gear,
electric motor parts, general machine parts etc.

Bronze Casting CAC406C 는 내압성, 내마모성, 피삭성이 좋습니다.
베어링, 슬리브, 부싱, 밸브시트링, 너트.켓너트.헤더 수도꼭지 부품, 일반 기계 부품 등.

Good in pressure tightness, abrasion resistance and machinability.
Use for bearing, sleeve, bushing, valve seat ring, water supply equipment fittings

and water service equipment fittings (such as nut, box nut, adapter, plug, union,
socket, ball valve, valve seat, stem, nipple and header) and general machine parts, etc.

Bronze Casting CAC407C 는 기계적 성질이 CAC406C 보다 약간 좋습니다.
베어링, 소형 펌프 부품, 일반기계부품등으로 사용됩니다.

Rather better in machinability properties than CAC406C.
Bearing, small-size pump parts, general machine parts, etc.
