Development of Brake Caliper Production Process with High Strength Al-Li Material

Article of Honda R&D Technical Review F1 Special (The third Era Activities)

Summary

A production process was developed that uses high-strength Al-Li materials to reduce the brake caliper weight. Anisotropy of material strength due to metal flow was eliminated with 3-axis multi forging, and an 8% increase in fatigue strength was achieved by T6 heat treatment with 3-stage aging. This is expected to increase the service life to 4 times that of current calipers.
