Brass threaded inserts made from high quality brass to BS EN 12164 CW 614N standards.
Brass threaded inserts benefit from excellent mechanical properties: corrosion resistance, efficient machinability and good electrical conductivity. They are generally more cost effective compared to steel(s) and are ideal for assemblies made out of thermoplastics, thermosets or composite materials.
Brass has a higher thermal conductivity compared to steel so inserts manufactured from it can be heat-installed more quickly than those manufactured from steel(s).
Performs better than steel for the following applications:
- In the presence of hot/cold water it provides excellent corrosion resistance
- Suitable for use in some marine environments (i.e. in salt water) although specific application requirements always need to be understood
- Good performance in cryogenic applications
- Can handle exposure to both mild alkaline solutions and non-oxidising acids, but strong alkaline solutions or oxidising acids should be avoided
- Very good corrosion resistance to petroleum based materials
- Good strength, nearing the tensile strength of low-carbon steel
- Compatible with industry plating surface finishes, including nickel, for both aesthetics and enhanced electrical conductivity
- Brass can be readily recycled and so could be said to be a ‘green’ material
- Brass can also be specified, ‘lead free’, and after careful process development by Tappex, ‘lead-free’ threaded inserts are now available
