6061-T6 has high strength, high hardness (up to HV90 degrees or more), good processing effect, and good oxidation effect. There are no trachoma pores, and the flatness is better. Improve processing efficiency and reduce material costs. This will be the best choice for low-price, high-quality materials. The 6061-T6 series is an alloy of aluminum, magnesium, and silicon. It is a heat-treated corrosion-resistant alloy. The strength and corrosion resistance are relatively good, and the uniformity is good.
