Where the Aluminum Finishing Always Comes First
When you need to give an aluminum surface the hardness of case-hardened steel while maintaining the light- weight of the aluminum, you need DURALECTRA-CHN. Our custom finishes will make your surface sapphire- hard, corrosion and abrasion-resistant, help it conduct and resist heat, give it lubricity, dielectric properties, and even color it. We make exclusive use of the SANFORD PROCESS®, a proprietary, hard anodizing that is so versatile it enables us to hard coat virtually all alloys (including 2000 series & cast) and to meet your particular requirements.
