As to materials, there are many many materials a solvent trap can be made from.You’re most likely seeking a straightforward numbered checklist of strong metals for solvent trap here, rated from strongest to weakest. However, you’re not going to get a solution so quickly.We will analyze from the following dimensions.
WEIGHT: STAINLESS STEEL > TITANIUM > ALUMINUM
We all know that when an aluminum spoon is placed in a sink, it will sink to the bottom. This is because the density of aluminum is greater than that of water: the density of regular aluminum is 2.7 g/cm3, which is 1 g/cm3 greater than that of water.
The density of stainless steel is about 7.9 g/cm3. The weight of stainless steel per cubic inch is 0.285 pounds, and the weight of stainless steel per cubic foot is 490 pounds.
The density of titanium metal is 4.51g/cm3, which is higher than aluminum and lower than steel, copper, and nickel, but its specific strength is at the top of the metal.
This is the worst possible place to add weight to your gun, so the lighter your solvent trap is, the better.
COST: TITANIUM> STAINLESS STEEL > ALUMINUM
In general, titanium will usually be more expensive than other metals because it is rarer than other metals, and because it is typically only found bonded to other elements which can make processing more expensive.
Aluminum is commonly less expensive than tempered steel. The cost of titanium is 5 times that of stainless steel, The cost of titanium is 5~10 times that of Aluminum. its MUCH harder to machine, much harder to forge, or to heat treat. It has more susceptibility to hydrogen embrittlement. The global supply is unreliable, meaning prices are not stable, It CAN catch fire, and if it did you would very likely not be able to put it out.
CORROSION: TITANIUM> STAINLESS STEEL > ALUMINUM
Aluminum has a high oxidation and corrosion resistance mainly due to its passivation layer. When aluminum is oxidized, its surface will turn white and will sometimes pit. In some extreme acidic or base environments, Aluminum may corrode rapidly with catastrophic results.
Stainless steel is made up of iron, chromium, nickel, manganese, and copper. The chromium is added as an agent to provide corrosion resistance. Also, because it is non-porous the resistance to corrosion is increased.
Titanium is resistant to corrosion thanks to a thin layer of oxide formed on its surface in the presence of air or water. It also resists cavitation and erosion.
WORKABILITY: ALUMINUM> STAINLESS STEEL > TITANIUM
Aluminum is fairly soft and easier to cut and form. Due to its resistance to wear and abrasion.
Stainless can be difficult to work with. Stainless steels are harder and are especially harder to form than aluminum.
Titanium is the most difficult metal to process.
CORROSION:TITANIUM> STAINLESS STEEL > ALUMINUM
Titanium is not as strong as people like to think it is. Titanium is valued for several advantages it has over steel (and also aluminium) but strength is not one of them. Its resistance to corrosion from the air (since it forms an oxide layer that stops the oxidation from going any further) and from acids (i.e. its not very reactive).
CONCLUSION:
Aluminum
Stay away from aluminum, unless weight is a huge factor.
Stainless steel
Stainless steel, is fantastic. Corrosion resistant, strong, inexpensive. But, heavy.
Titanium
Titanium, very strong, very lightweight, harder to machine and paint, increasing cost.And remember, this weight is being attached to your gun all the way at the end. This is the worst possible place to add weight to your gun, so the lighter your suppressor is, the better.
