You can SoCM them to something such as Ommel Tooth or Diamond...but this isn't really a wise move. For best results, gauntlets should be made of a strong material with a high flexibility rating like Golden Eagle Feather. Stiff materials hurt your Dexterity rating; imagine trying to swing a sword with gloves made out of rock!
If you are aming for an unarmed fighter, it might be wise to enchant your gauntlets at least several levels as enchantment level of your gauntlets is used when the game calculates your unarmed damage.
There are two kinds of ability enhancement gauntlets to be find in the dungeons, similarly to boots. The formula is the same - higher enchantment levels increase the targeted ability accordingly. These gauntlets have a base enchantment of +1, as opposed by +0 for normal gauntlets, so if you find e.g. a +0 gauntlets of strength, those are actually disenchanted.
