The investigation is a part of a Scandinavian research
project "Nord-plade", in which the formability of
high-strength low-alloy (HSLA) --steels and high-strength
aluminium alloys is studied. The press behav-iour of
these materials is in many ways inferior to mild steel.
Conse-quently, there is a great need for test runs where
reusable prototype or short production run tools are
needed. However; the high strength of the sheet material
limits the choice of possible prototype tool materials.
In the present work the mechanical and tribological
properties of zinc-aluminium casting alloys containing 4
- 16 % Al were investi-gated. Laboratory and production
tools were manufactured from the alloys showing
preferable properties in the preliminary study. Their
castability and durability in practical deep drawing were
The strength and ductility of the alloys generally
improved with in-creasing aluminium content. On the other
hand their castability and tribological properties
deteriorated when higher amounts of aluminium were used.
The alloys containing 8 or 12 % Al were found to meet the
practical requirements for successful forming of high
strength steel sheets up to 400 MPa yield strength.
