Nickel-Chrome Dental Alloy for crown and bridges(columnar)
The best choice for high performance price ratio of fixed dentures
--------- German technology, continuous casting process, the most advanced standard
of alloy casting
· Stable product quality, no refractory residue,
Less impurities, satisfy the requirements of
European quality.
· Stable Expansion coefficient, Suitable hardness,
meet the demand of all the porcelain powder,
the Combination of alloy and porcelain powder is more densified.
· Easy to melt, Good fluidity of molten steel, High casting
successful rate for making perfect crown and bridges
· less oxide layer of casting, Good toughness,
High strength, easy to polish, High brightness,
easy to get the smooth, bright crown and bridges.
