Wheelbuilder High Strength Aluminum Nipples are made from a 7000-series aircraft alloy, making them significantly stronger than the alloy nipples produced by most manufacturers. 

We proudly use Wheelbuilder high-precision aluminum nipples for all of our custom built wheels with alloy nipples for the following reasons:

• Using a high strength aluminum alloy significantly improves issues with deformation across the flats in high tension applications.
• High tolerance of thread hole concentricity dramatically reduces potential for nipple head failure caused by material thickness variance at the seat.
• Wheelbuilder's aluminum nipples are anodized with a proprietary technique that individually fixtures each nipple to guarantee finish quality consistency across a wide a spectrum of colors.
