Since 1922, Ampco Safety Tools has established the global benchmark for non-magnetic, non-sparking, and corrosion-resistant hand tools. Manufactured from the aluminum bronze alloy invented by AMPCO, they produce over 2,000 types of tools, nearly all of which are made in the USA. These tools are crafted from FM Approved alloys, independently tested and verified to present no known risks in MRI environments with static magnetic fields up to 3-Tesla and maximum spatial gradient magnetic fields of 720-Gauss/cm or lower.
