TPS has been asked by some customers to respond to the Aluminum vs Steel debate on the bases.
As most know, the debate regarding the aluminum vs. steel debate has been going on since about the first lawn chair hit the sandy beach in Florida.
We fully recognize, understand and appreciate the hardcore and die-hard folks who wish to have real steel on their sticks. About half of our company's employee's have the same point of view. However, the reality of the application of the two materials is not so cut and dry. When you get into comparing strength differences between aluminum alloys and steel alloys, it's like comparing apples to bananas. The thermal coefficients of expansion are different as well, which has nothing to do with the strength, which has already been pointed out.
The strength (the part that truly matters) of the 7075-T651 Aluminum Alloy is far stronger than is even remotely necessary for the application that it has been tasked to accomplish in this discussion. TPS has and is in the process of having another independent testing done of it's 7075 Aluminum rings and bases done again. The first testing, done last year for customer contract requirements, involved our TSR 30mm (30580) 7075 Aluminum alloy rings. Our rings withstood a whooping 25,000 G's before failure. Even at such numbers of G-Force's, they still didn't catastrophically fail, only the clamps gave out.
As for the thermal problems of a rifle heating up Un-proportiantly to the steel, TPS doesn't see that as an issue with rings and bases. If the bases were mounted directly onto the barrel, there may be a reason for concern, however in most circumstances the temperature increase on the receiver of a turnbolt rifle is so insignificant, that it would be almost undetectable in the mount. Even if the base was steel, mounted directly to a barrel which was being fired and consequently thermally heated from firing, the base would not heat evenly with the barrel. Because the mount would be exposed to un-proportiant amount of airflow, the mount would continue to be lower in temperature than the barrel. The transfer of heat between the barrel and the rail itself would be also different, due to the inability for the two similar metal to bond together at a molecular state.
All in all, as always, it makes some darn good discussions around the firepit, but in actual practice, only one thing really matters. Complete your mission and come home safe.
