Alloys and Dimensions
HOVADUR® Alloys The basic materials for all alloys are pure metals such as copper, nickel, cobalt, chromium, beryllium and zircon. These metals are prepared in correct quantities and filled into the crucible of the vacuum furnace.
Recharging during the melting process is carried out via a lock chamber. Once the melting process being finished, the alloy is cast under vacuum into one or several moulds.
Due to this procedure under complete absence of air, a very high purity and quality of the alloy are achieved. Negative environmental influences are completely excluded.
We supply HOVADUR® alloys in the following formats: • Bars >>> • Discs and rings >>> • Forged round bars and plates >>> • Ingots >>> • Finished parts >>>
SCHMELZMETALL supplies forgings up to a weight of 1500 kg. Pieces cut from plate, special dimensions and profiles can be produced according to your requirements. Due to our extensive stock, we are normally able to supply you within a very short time.
Your product has to have special properties? No problem! Our specialists like meeting new challenges.
HOVADUR®: Special alloys for special applications SCHMELZMETALL alloys are in demand all over the world whenever special values concerning thermal conductivity, electrical conductivity, strength and gliding properties are requested.
We stand for competent technical advice, we supply pre-machined parts or take over the revised construction of your existing parts, of course on demand also according to your sample. Smooth order processing is ensured due to the quality and the wide range of our machinery as well as many years of experience of our skilled and committed production team.
