HGT PRECISION MATERIALS
Where we use aluminium alloy, we’ve chosen the best 7075-T6 heat-treated billet.
While it’s an expensive material, it is the strongest aluminium alloy available and is the industry standard for many aerospace and military applications.
7075-T6 alloy is as strong as many steels with a tensile strength of 85,000 PSI. The strength and rigidity of a gearbox casing are crucial for gear performance, so we elected not to compromise performance by choosing a material that has flex as part of its metallurgy.
We use the highest quality European grades of case-hardened alloy steels from qualified steel mills in our HGT Sequential Gearboxes. You may ask what the difference is? Well; not all material sources are the same. Some steel mills control the quality strictly while others not so. If the mechanical or chemical properties of a steel grade vary, this affects the heat treatment process which is critical to gear performance and longevity.
