QTi® Copper Titanium Core Pins and Inserts

Core pins and inserts in dies are subjected to high thermal and mechanical stresses in GDC, LPDC & HPDC Casting process. Core Pins made of steel can withstand the wear but are unable to extract heat quickly due to poor thermal conductivity, which results in uneven shrinkage and porosity in the casting.

?Copper Titanium Core Pins and Inserts provide an excellent combination of high thermal conductivity and good wear resistance. QTi Inserts are much harder than other competing copper alloys and exhibit thermal conductivity up to 5 to 10 times greater than steel pins. High hardness of Copper Titanium alloy provides excellent wear resistance. This significantly increases the life of the pin, and dramatically reduces casting rejections.

?QTi® alloy provides excellent corrosion resistance and has inherent lubricity and galling resistance. QTi® pins can be coated with a super-hard PVD coating thus increasing their surface wear resistance even more, without any compromise on the thermal conductivity. The coated pins and inserts can be used in very demanding applications and the integrity of the casting can be maintained and rejections reduced.
