Forging compresses a 6061 aluminium billet into a continuous grain structure, while casting leaves a dendritic structure with internal porosity. The result is higher tensile strength and elongation at a lower weight, so a forged wheel can be both lighter and tougher than a cast wheel of the same size.
Every SHB batch ships with material certificates and dimensional reports, and sample wheels from each new design go through load fatigue and impact testing before release.
