Has there been any hardcore testing on any of the all Titanium cans? Any long term effects like erosion/damage?
|
| I have not heard of any offical "torture test" for titanium based cans like the Ti-Rant. I haven't dealt with materials since the course I had on it sophomore year in college, but in terms of erosion resistance, wouldn't you focus on the material hardness? I would suspect that you would want the same properties of Inconel since it makes a very good rifle can. |

Quoted:
Bump for interest. By all my knowledge of materials engineering I can't imagine why titanium would be inferior to steel other than the remote possibility that its lower density outweighs its superior thermal properties... ...which it shouldn't. Steel it may compare relatively well to, as steel is also not a high temperature material. Low strength at high temperature, coupled with low density making it heat faster. Also softer than inconel at higher temperatures. The combination of these should make it significantly less durable than inconel in high rate of fire, centerfire applications. |
| Titanium has excellent corrosion resistance. The galvanic series is a good wet finger method for corrosion resistance. In most cases the higher on the table the metal is, the more prone to corrosion it is. Obviously this can change depending on the environment. Notice that Titanium is at the bottom of the table. |

True, titanium has good chemical corrosion resistance, but I wouldn't think that you would need to worry about electrochemical corrosion in a suppressor. I would think that erosion, or the abrasion of the baffle material by tiny particles (in this case, gun powder residue) would be a greater concern. In this case, you would want a harder material. |

Titanium is extremely hard even at high temperatures. What I was getting at was that in order to erode the material you would first have to compromise it with corrosion. Also I agree that there should not be any substantial electrochemical component to corrosion in a suppressor. I originally wanted to point to the activity series which shows general chemical resistance. However I could not find a link for that with Titanium in it so I linked the galvanic series which follows the same trend. |

I've been shooting Ti suppressors for about 6 years. I also have shot some AAC, Gemtech and Surefire cans for demo and testing.. Some of the Ti cans sound the same but weight less. If you are shooting FA and suppressed, you might want to use inconel / SS.
I'd take a SWAG 90% of all of us on ARFcom shoot at a rate that makes Ti just fine for durability. I've had no issues with either my thread on, or muzzle brake mounted cans. |
