Nickle chromium alloy gained importance in the 1930s due to the cost of gold. Ni-Cr alloys have adequate properties for use with ceramics. The hardness and elastic modulus of the Ni-Cr alloy allows for the use of a thinner cross-section of material; the thinner cross-section provides more space for porcelain veneering while still offering good resistance. Another advantage is their linear thermal expansion coefficient, which is similar to that of veneering porcelain. The similarity in thermal expansion reduces the risk of cracks and fractures during processing. Nickel sensitivity may be a concern with these alloys. The patient’s sensitivity to nickel must be carefully and thoroughly evaluated when selecting these alloys. [-record from]

  1. Instructions for use

Waxing: Minimum metal thickness (after grinding) should be 0.3mm. Waxing could be as thin as 0.3mm to 0.35mm


A-Direct for single units. Sprueing should be 6mm in length. Based on the size and the thickness of crowns use 6-8 gauge sprues.

B-indirect for multiple units. Use straight 8 gauge sprue, about 3 or 4mm in length and connect it to the unit.

For long spanned bridges use and additional sprue connected to the last unit.

Investing: use high heat investments. Follow the manufacturer’s instructions carefully. After investment has set, scrape the top of the investment to allow gases to escape.

Burnout: Place the ring in the furnace at room temperature, increase the temperature to 980-1050°C, with one hour holding time. Add 10/15 extra minutes for each additional ring.
