GUNMETAL |
|||
Most economic and widely used bearing material. Good waer and sliding properties. Due to high lead content good machinablity. |
|
||
TIN BRONZE |
|||
Good strenght combined with best wear resistance and slidig properties. Recommended alloy when dimensional accuracy is required under heavy, shock type, loads. Doesn’t adapt to edge loading as well as leaded tin bronzes. Good salt water and chemical corrosion resistance. Mating material is recommended to be hardened. |
|
||
LEADED TIN BRONZE |
|||
For grease lubrication or when the lubrication is intermittent leaded tin bronzes are your choice for the product. Lead acts as a dry lubricant during poor lubrication. Adapts to edge loading better than tin bronzes. Best alloys for water lubrication. Good resistance to sea water corrosion. |
|
||
ALUMINIUM BRONZE |
|||
High strenght and corrosion resistance are the main reasons to select aluminium bronze. Sliding properties and wear resistance are lower combined to tin bronces. Mechanical properties are close to some structural steels. Many machine parts can be produced from aluminium bronze when checmical or sea water environment cause risk for corrocion of steel parts. Good lubrication required on slide bearing applications. |
|
||
MANGANESE BRONZE |
|||
High strenght yellow brass alloys stand up with their relatively good mechanical properties combined with good machinability and relatively good sliding properties. High zinc content makes these alloys prone for dezincification on sea water environment. Wear resistance and sliding properties leave behiind those of tin bronzes. |
