Description of material
|
|
HOVADUR® B 10 is a nickel-free copper aluminium alloy (aluminium bronze). The main characteristic of the material is a
very attractive combination of good strength and thermal conductivity together with good sliding behaviour and
remarkable corrosion resistance.
Due to the melting and casting procedure employed by SCHMELZMETALL, HOVADUR® B 10 shows remarkably less tool
wear in case of machining compared to other aluminium bronzes.

Processing instructions
Hot forming
HOVADUR® B 10 is very suitable for hot forming at temperatures of about 920 °C to 700 °C. According to the degree
and the kind of forming, heating to 800 °C up to 850 °C is sufficient. After forming, cooling of the material is recommended
at inactive air.
Cold forming
Basically, HOVADUR® B 10 is not suited for cold forming. If nevertheless a certain forming is executed, a thermal
treatment after forming according to the instructions in the next paragraph is recommended.
Heat treatment
After hot and (possible) cold formings, a homogenizing and tension reducing annealing at a temperature between
600 °C and 650 °C during 2 to 5 hours is recommmended.
Machining
In normal condition, HOVADUR® B 10 can be machined easily with standard hard metal tools. Material has a tenacious
character.
Eroding of HOVADUR® B 10 is more difficult due to its better electrical conductivity compared to steel. HOVADUR® B 10
can be grinded without taking any special measures. Polishing is guaranteed.
Joining
HOVADUR® B 10 is suited for soft soldering as well as hard soldering. Concerning hard soldering, a (small) loss in
hardness is to be expected. A very lowly melting silver brazing should be used.
HOVADUR® B 10 is very well suited for joining by welding. Build-up welding is suitable, too.
Attention must be paid to sufficient extraction and filtering of welding fume.
Application examples
Due to its attractive combination of properties, the alloy HOVADUR® B 10 is excellent for many applications. Typical
examples are bearings, guide bushes, sliding elements and wearing plates in various operating conditions, but it is also
used for inserts in steel tools for evacuation of heat.
