Regarding castings in El-copper and Aluminium- Bronze, we consider ourselves beeing specialists, but all standards of copper-alloys are naturally awailable.
In the scheme below You have a review of the most common used copper-alloys with analysis and mechanical properties.
As an alternativ to casted parts,
we are able to manufacture
forged Contact Clamps and Pressure Rings
in material SE-CU ( CU > 99,9 % )
with an electrical conductivity of
min. 99 % IACS.
Thermal Conductivity 386 W/m-K.
Elasticity 110 kN/mm˛.
Tensile Strength 200-360 N/mm˛ and
0.2 Yield Strength ~50-320 N/mm˛.
