The Morelli Stainless Steel Round Hard Wire Ø.028″ is a heavy-side round section of 0.70 mm, drawn hard from chromium-nickel stainless steel and supplied on a 50 g roll of about 16 m. Stiffness rises steeply with diameter, and at this gauge the wire behaves as a structural member rather than a wire that follows the hand.
Key Features
0.70 mm structural section — stiff enough to act as a load-carrying member in a fabricated appliance.
Hard temper — the formed geometry is maintained without progressive opening of the bends.
Round profile — permits bends in any plane, with no section orientation to manage.
Uniform drawn diameter — consistent fit where the wire passes through tubing or is set into acrylic.

Clinical Applications
Load-bearing parts of removable appliances formed from a section that resists flexing in service.
Components set into acrylic where the uniform 0.70 mm diameter gives a predictable fit.
Heavy bending at the bench using pliers sized for a structural gauge.
Which gauge stops flexing and starts supporting?
At 0.70 mm this hard-drawn round wire works as structure, not as a follower of the hand.
