2. Second to Care: Material
Good material for good performance. The tensile strength of 6061-T6 Aluminum Alloy can reach as high as 310MPa, Compared to 6061 Aluminum Alloy(125MPa), an increase of 150%.
T6, which means metal state, there is a difference between 6061 and 6061-T6.
3. Forming Process: Forging or Casting?
Generally, forging must undergo continuous punching to form, with tight internal organization and good mechanical properties. And casting is to cast molten aluminum on a sand mold and wait for it to cool before machining, the internal structure is loose, the density is low, and the mechanical properties are lower than forging.
4. Anti-rust process: Dacromet, Chrome Plating, Galvanizing…
Normally say, Dacromet is a "green plating", will not producing any waste water or waste gas during the process. Besides, the anti-rust performance of Dacromet is better than chrome plating and galvanizing. What’s more, chrome plating may produce “Hydrogen embrittlement”, which is harmful for metal.
5. Brand LOGO:
Logo on the wheel spacers adapters, which means responsibility. Remember to choose those spacers with brand logo. To ensure the after-sales service.
