Magnesium Chassis Parts for Motorcycles
Examples of large, cast magnesium parts with thin sections
- Lighter weight
- Higher quality
- Higher precision
- Design appeal
- Cost reduction
Based on our CF (controlled filling) die-casting technology for aluminum, Yamaha was able to successfully develop casting methods yielding even melt flow and solidification for magnesium-specific part designs; optimized control of vacuum degree in the mold cavity, mold temperature, and melt injection speed; and melt control that minimizes impurity content. These and other achievements made it possible to cast large magnesium parts with thin sections, thereby practicalizing the use of magnesium for large motorcycle chassis parts. Following the casting process, these magnesium parts are given a special highly corrosion-resistant surface treatment prior to painting, bestowing them with strength and corrosion resistance equal or superior to identical aluminum parts (based on Yamaha standards).
