Cast titanium tubes embedded material performance requirements
     Medicine to obtain a good casting cast titanium tube size to the embedding material hardening and

thermal expansion compensation titanium alloy pump expanded metal casting shrinkage is the most commonly used method. Titanium

tube casting line shrinkage of 0.9-1.0%, the total expansion required when casting titanium tubes embedded

material must be able to titanium tube compensate for the contraction of the range of metal and titanium tube system in

principle, with the cast of embedding material not mix. Therefore, the choice of cast titanium with embedded

material conditions must have the following conditions:
     1. Rarely react with titanium.
     2 to obtain good surface properties.
     3 castings are not titanium casting contaminated.
     4 titanium tube shrinkage compensated moderate swell.
