Tha na stuthan uilinn radius goirid a thathas a’ cleachdadh anns an loidhne riochdachaidh cunbhalach againn a’ toirt a-steach measgachadh de aloidhean. Tha uilleanan radius goirid air an dèanamh bho stuthan àrd-inbhe leithid Hastelloy, Monel, Nickel, Inconel, Titanium, Tantalum, Stàilinn Stainless, Alloy Steel, Carbon Steel, Copper Nickel 90 \/10 agus Copper Nickel 70 \/30. Faodar na criathran sin a dhèanamh ann an grunn ìrean gun uilinn radius goirid leithid ASME \/ ASTM SA \/ A403 SA \/ A 774 WP-S, WP-W, WP-WX, 304, 304L, 316, 316L, 304 \/304L, 316\/316L, DIN 1.4301, DIN 1.4306, DIN 1.4401, DIN 1.4404.
