Aluminum Mock Wafers

Durable Mock aluminum wafers are durable. Unlike Silicon, they cannot be broken! Al wafers are medium to dark matte gray/black in color, and are 10 to 15% heavier than silicon wafers. Their diameter is within SEMI guidelines. Al wafers are perfect for prototyping and prototype manufacturing processes. These products also make handling wafers easy and safe.

Aluminum Mock Wafers Silicon Replacement

Used as durable, shatterproof replacements for semiconductor silicon wafers for training, robotic calibration,450mm mock aluminum substrate 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.
