A sponsored campaign was launched to develop a magnesium alloy wheel rim for the European Formula 3 Racing Series
Funke, in collaboration with the customer, developed the design of the wheel and the casting technology in several cycles until all requirements, constraints and mechanical properties were satisfied.
One of the special challenges was to achieve a 12% Elongation-to-Break/Ultimate Elongation parameter through the entire cast part. Replacement of previously used aluminium wheels with the newly developed light-weight magnesium alternative resulted in a significant weight reduction translating into tangible improvement in driving dynamics in the field for the cars.
After a successful test stage, the entire Formula 3 Racing Series was equipped with these wheels for two racing seasons
2000 Wheels were manufactured for this purpose.
