I'm not sure aluminum is all bad, but there's certainly some compressors out there that won't have a very long life in continuous use. There's all cast iron, the traditional material(heavy, too). There's aluminum blocks with cast iron sleeves and there's all-aluminum with plated cylinder bores. The last are generally the oilless cheapies you see in Harbor Freight and the like, generally direct drive(no belt). They have a nylon or teflon piston seal that wears and the internals are generally alloy, too. They have a number of advantages, they don't leak oil if they're tipped over, one guy can usually horse them around and they're cheap. Also, no possible oil contamination, although you still have to have a water trap on them, so that's not a really big deal. Mine gets the job done, when I get some place permanent, hopefully not too long from now, I'll get a large cast iron stationary beast. The aluminum with cast iron sleeve compressors looked good, much lighter than all cast iron and had a higher rating than my oilless, but won't fit in the back of my car and would leak oil if tipped over to haul around. ë žC u need depends on your circumstances, financial and otherwise.
