Aluminum Mock Wafers Silicon Replacement

Used as durable, shatterproof replacements for semiconductor silicon wafers for training, robotic calibration, particle shield, identification, equipment demonstration and promotional applications. Mock wafers are precision manufactured from 6061 T-6 aluminum alloy. Each Al wafer is chemically etched and heat-treated to improve flatness and surface hardness and durability. It is a medium to dark matte gray/black in color. Each wafer is approximately 10% to 15% heavier than a silicon wafer of similar size and profile. Dimensions of diameter and notch are within SEMI standards. Mock wafers can include silk-screened artwork, engraving, color or other modifications on a custom basis.
