Ames Flat, Raised, Round, Convex, Cylindrical and Vee Anvils
There are 5 types of Ames anvils available for your Ames tester. You can reverse the position of your penetrator and anvil to conduct internal hardness tests as well.
The anvil plays an important part in testing hardness. Using the correct anvil with your Ames tester ensures you will receive valid readings. The Anvil makes sure your work does not move during the work build-up step of hardness testing. Anvils are interchangeable (see video below).
The chart below shows what each anvil looks like and how it works:
Raised Flat Anvil:
Raised flat Anvils were designed to put the least amount of pressure on very thin stock. Of course, less pressure equals fewer indentation marks as well. These anvils are generally used with superficial testers.  You can test materials as thin as .006 with an Ames testerÂ
Raised Flat Anvil 1/4″
The correct anvil helps ensure valid readings by making sure work does not move during load buildup. Anvils are interchangeable part number T-1129
Raised Flat 1/8″
The correct anvil helps ensure valid readings by making sure work does not move during load buildup. Anvils are interchangeable part number T-1130
Convex Anvils
You can use Convex anvils to test the inside hardness of tubes. this anvil comes standard with our Model 1-ST superficial tester.
Convex Anvil 3/4″
The correct anvil helps ensure valid readings by making sure work does not move during load buildup. Anvils are interchangeable part number T-2227
Convex Anvil 1/2″
The correct anvil helps ensure valid readings by making sure work does not move during load buildup. Anvils are interchangeable part number T-1127
Cylindrical Anvil
You should use a cylindrical anvil to test large round stock.
Cylindrical Anvil 1″
The correct anvil helps ensure valid readings by making sure work does not move during load buildup. Anvils are interchangeable part number T-4226
Cylindrical Anvil 3/4″
The correct anvil helps ensure valid readings by making sure work does not move during load buildup. Anvils are interchangeable part number T-2226
Cylindrical Anvil 1/2″
