Description
of Material |
|
Age
hardenable Cu - alloy with high electrical and thermal conductivity together
with a very high degree of hardness and strength. These
properties give a considerable increase in electrode life especially in
cross-wire welding applications. |

Processing Information |
Hot Working Mallory
100EH can be easily hot
worked at 900 - 7000C approx.
Severely oxidising protective furnace gasses should be avoided.
The forming operation should be followed by rapid cooling. Cold-forming Mallory
100EH can be cold-worked
well in a solution heat-treated state. Perform intermediate annealing
at around 8000C followed by rapid cooling. ` Heat
Treatment Mallory
100EH should be solution
heat-treated prior to temperature hardening. Solution
heat-treating 15
- 60 minutes at 900 - 9600C followed by cooling in water. Check
hardness measurement: max. 110 HB Check
conductance measurement: approx. 125m/Ohm x mm2 Hardening:
1 - 5 hours at 460 - 5000C followed by slow cooling Machining It
is recommended that Mallory
100EH be machined in its hardened state (e.g. turning, shaving,
milling). Ensure adequate
ventilation. When drilling
it is advantageous to use drills with an extended angle of twist. Joining
Work Mallory
100EH can be soft soldered
on prepared surfaces. Brazing
with low-melting point silver fillers can also be implemented.
However, a drop in the hardness is likely when the soldering
temperature cannot be limited to 4000C. Welding in accordance
with the TIG method is possible but preferably in a solution heat-treated
state. Ensure good ventilation
in so doing and provide additional extraction of welding fumes by suction. |
