CuSn6 is a bronze alloy reinforced through solid solution strengthening, containing 6% tin. This alloy exhibits high strength and favorable spring characteristics, maintaining sufficient conductivity, making it ideal for cold forming processes. It is characterized by its wear resistance, excellent corrosion resistance, and ease of soldering.
It is commonly used in the production of stamped parts, connectors, spring contacts, and springs, as well as in metal hoses. The alloy finds applications across various industries, including the paper industry, shipbuilding, apparatus construction, and both electrical and mechanical engineering fields.
The CuSn6 material, as referenced in DIN1791, is a type of bronze alloy used for manufacturing bushes. This material has specific properties that make it suitable for such applications, including good wear resistance and strength. The designation “CuSn6” refers to the copper-tin alloy with approximately 6% tin. The “DIN1791” likely refers to a specific standard or specification related to this material or product, although the exact details of this standard are not provided in the search results.
The term “tolerance H6” refers to the dimensional tolerance of the bushes, which is a critical factor in their fit and function in mechanical assemblies. The H6 tolerance is a standard metric tolerance that specifies the size and allowable variation for the bushes, ensuring they fit appropriately with the corresponding shafts or housing components. While the exact dimensions for an H6 tolerance can vary based on the nominal size, it generally indicates a tight tolerance level suitable for applications requiring precise fit!
The DIN 1791 standard is presumed to define the specifications for bronze materials like CuSn6, but the exact details of this standard aren’t available in the provided information. The H6 tolerance mentioned is based on the ISO 286 International Tolerance Grade, specifying the permissible size variation for shaft dimensions. For instance, a 1.00” hole with an H6 tolerance would have a permissible size deviation ranging from +0.0000 to -0.0005 inches.
Lubricating holes in bronze bushes serve the crucial function of distributing lubricants, such as grease or oil, to minimize friction and wear between the bush and its counterpart. Grease is particularly favored for solid bronze bushes because of its viscosity and ability to hold contaminants away from the bush surface while providing sustained lubrication.
Wrapped split bronze bushes are engineered to support both radial and axial loads and can include customized features like grease reservoirs for extended lubrication or graphite inserts for self-lubrication. Similarly, self-lubricating bronze bearings might incorporate oil impregnation or graphite plugs, ensuring continuous lubrication over their lifespan.
In essence, CuSn6 DIN 1791 wrapped split bronze bushes with an H6 tolerance and lubrication holes offer robust, corrosion-resistant bearing solutions. These bushes are adaptable to various load conditions and can include specialized lubrication options to boost their performance and durability.
The DIN 1791 standard, established in 1973, pertains to cold-rolled strips and strips cut to length from copper and wrought copper alloys. This standard specifies the dimensions for strips ranging from 1.0 to 4 mm in thickness and up to 1000 mm in width for manufacturing lengths, as well as for strip cuts from 0.1 to 4 mm thick and up to 500 mm wide in lengths over 500 mm. It’s important to note that DIN 1791 has been superseded by newer standards, specifically DIN EN 13599 and DIN EN 1652, which may contain updated specifications or requirements!
