Yes, makes total sense. "Titan"-strong + "al" - aluminum. "Titanal". Practically wrote itself.
"The use of aluminium in alpine ski design dates back almost 50 years. On the basis of initial tests carried out in the 1960s, skis utilising an aluminium sandwich construction were the object of ongoing development, the first recognisable successes were achieved at the 1964 Winter Olympics in Innsbruck. From this point onwards, AMAG focused on the creation of a high- strength aluminium alloy for use in the winter sports field.
This chemistry teacher is a little disappointed that she missed the al = Al = aluminum. Titanal = “strong aluminum” (alloy).
My SR 83’s and SR 100’s have no top sheet; the metal layer is the top sheet. Only a few small nicks so far which I’ll file when I put summer wax on this weekend.
Still waiting to see what the shop says about the extra holes, and what Kastle says about the damage to OP’s skis.
