I suspect the bad editing job cut something out that we needed to know.  The brain cavities of the Alien don't have blood, hence no acid.  That's why the Predator's blade also didn't melt when it sliced that Alien's brain.  The metal weapons melt only when drenched in acid.

Not all weapons are necessarily made of metal.  We know for example that the Predator's spear is made of something lighter than metal that has the ability to collapse into such a small size.  Could be a ceramic in which case it would be immune to acid.

It's not uncommon for gladiars going into a ring to have several weapons made of different materials.  I suspect the netting could even be a polymer-based resin that contracts when exposed to cold or air.  We have materials today that behave exactly this way.
