Cuptin (CuSn) Tin Bronze

You can find the material properties of Cuptin® (CuSn) in the "Technical Details" tab. All mechanical and material properties of Cuptin® (CuSn) tin bronze are specified within this tab.

Cuptin® CuSn series can be used in low and high-speed bearings, worm gears, gear manufacturing, sliding and bush bearings, and as reinforcement pins in heavy vehicles with high strokes. The usage areas of products in the Cuptin® series are listed below:
Cuptin® 1A: Used for the bearing of low-loaded, high-speed operating, 300 HB hardness or lower hardened shafts. It is a medium hardness material used in applications such as the casting of corrosion-resistant items like valves exposed to seawater.
Cuptin® 1B: Used for the bearing of low and medium-loaded, very high-speed operating, 300 HB hardness or lower hardened shafts, in sliders and sliding bearings. It has excellent lubrication properties.
Cuptin® 2: Used for the bearing of medium-loaded, medium-speed operating, 300 HB hardness shafts, and gears. It has high corrosion resistance and toughness.
Cuptin® 2-Zn: Used for the bearing of medium-loaded, medium-speed operating, 300 HB and lower hardened shafts. It has very high corrosion resistance against seawater.
Cuptin® 3: Used for the bearing of medium and high-loaded, medium-speed operating, 300-400 HB hardness shafts, and gears. It has high strength and corrosion resistance.
Cuptin® 3-Ni: Used for the bearing of medium and high-loaded, medium-speed operating, 300-400 HB hardness shafts. Due to the addition of Ni, it has higher toughness, yield-tensile strength, and hardness compared to CuSn12.
Cuptin® 3-Pb: Used for the bearing of medium-loaded, medium-speed operating, 300-400 HB hardness shafts. It is easier to process due to the addition of lead compared to CuSn12.
Cuptin® 4: Used for the bearing of medium and high-loaded, medium-speed operating, 300-400 HB hardness shafts. It has higher yield-tensile strength and hardness compared to CuSn12 and CuSn12Ni. It has lower toughness.
Cuptin® 5, Cuptin® 6, Cuptin® 7, Cuptin® 8: Due to their low hardness and strength, they are used for low-loaded and very high-speed operating unhardened shafts. They are alloys with excellent lubrication and bearing properties, with the lubrication property increasing depending on the lead content in the structure. They are suitable for use in bearings, especially in cases where lubrication is difficult and inadequate.
