Alumec 89 is a high strength aluminium alloy
supplied in the form of hot rolled, heat treated
plate. It undergoes a special cold stretching
operation for maximum stress relieving.
Thanks to its high strength and good stability,
Alumec 89 has become widely used in the
tooling industry.
Delivery condition: heat treated to 146–180
Brinell.
Alumec 89 has the following characteristics
which make it suitable for many types of tools
especially plastics moulds:
Excellent machinability - High cutting speeds, reduced machining time, lower tooling costs, quicker deliveries.
Low weight - The low weight, which is approximately 1/3 of the weight of steel, allows easier and more convenient tool handling. Low inertia makes it possible to speed up closing and opening of moulds.
High thermal conductivity - Cycle times are reduced and less complicated cooling systems may be used.
Good stability - A special stress relieving operation guarantees minimal deformation during and after
machining.
Good corrosion resistance - Good resistance against all commonly used plastics materials.
Suitable for surface treatments - Alumec 89 can be hard anodized, hard chromium or nickel plated for increased hardness, wear resistance and corrosion
resistance.
