LeClaire Manufacturing’s aluminum castings go on industry leader’s machinery in the agricultural field. Being only a third of the weight of steel or iron, naturally non-corrosive and with numerous alloys available to meet most strength requirements, aluminum is the present and the future of the agricultural industry’s castings.
Weight advantages allow for greater gas mileage and less compaction on fields which translates to lower expenses and higher harvests. Utilizing LeClaire Manufacturing’s aluminum casting expertise and guidance, many customers have found functional, weight and cost benefits by converting iron and steel weldments and castings, to a lighter, non-corrosive and strong aluminum casting.
WHY IS ALUMINUM SO CORROSION RESISTANT?
Aluminum is a very active metal, meaning that its nature is to oxidize very quickly. While a weakness for most metals, this quality is actually the key to its ability to resist corrosion. When oxygen is present (in the air, soil or water), aluminum instantly reacts to form aluminum oxide. This aluminum oxide layer is chemically bound to the surface, and it seals the core aluminum from any further reaction. This is quite different from oxidation (corrosion) in steel or iron, where rust puffs up and flakes off, constantly exposing new metal to corrosion. Aluminum’s oxide film is tenacious, hard, and instantly self-renewing.
