Polycoat and the alloy frame - questions

[briang2ad]

"do not buy"  is just that.  Yes, 'shot' is a bit hyperbolic - but silver means the anodizing is worn through and the aluminum is unprotected - so people who have been running SIGs for decades generally tell you to avoid buying such guns. Can one run a gun with silver slide rails and just keep grease on it?  Yes.  But I would not buy such a gun.  And, in the case of SIG and hardened Stainless slides on aluminum rails, it wears a bit faster.  The hard anodizing IS a hardening and a finish.  It protects.  Once off, the guns wears much faster.  Grease prevents this. Drive accordingly. 

CZs come silver (from what I've seen on alloy framed guns), and that is why I asked.

 While the hard anodizing may provide an additional hard coating to the surface you can be sure the frame of the Sig is tempered/hardened the same as any other quality firearm.

Yes, but bare aluminum is much softer than steel.  It is just not as durable. Hence my question about CZs and alloy frames.

Yes I know why you asked your question.
Yes no kidding aluminum CAN be softer than steel depending upon the aluminum alloy grade and the steel grade. Modern high grade aluminum alloys often rival many steel alloys. All metals are tempered or annealed to provide a decided strength factor and wear resistance according to the intended application.
This is a tired old beating a dead horse discussion.
Quality aluminum gun frames like what CZ uses in the PCR and P-01 and so on will last longer than most of their owners.

I do believe that steel in guns is always harder than tempered Al.  For what it is worth:

Al T6 Rockwell 60

Stainless Steel 70

I do believe that in the case of SIG, HK, CZ P series, etc., the Nitrocarbeurizing hardens it further.  No, likely no chance of wearing out a P01.  But, the hard anodizing adds an extra layer of protection and adds dimension to the metal on a SIG. 

Also, when the P01 came out I do believe CZ mentioned something about the frame alloy that was an improvement over the PCR.

Well, I would think CZ pulled out all the stops to achieve NATO approval for the P-01 and an expanded International market. 
I realize this thread is about durability of frames and requirements for refinishing, however I do wish CZ would revisit the 75 series compacts and Nitride the slides and barrel exteriors like they've done on the more recently designed P-07/09/10 series. Clearly the most durable finish.  Wishful thinking I suppose.
Anyhow...as Sir Vis has stated, my P-01's will undoubtedly outlast me.

I would love to see them finish the 75 series like the p-series but that would require them to clean the frames and slides up and remove all the imperfections that the polycoat hides. I just don't see it happening either at this late stage of production. They are putting their eggs in the polymer striker fired basket now.

Not to get off topic, but I nitrided one of my PreBs and it was NOT bad a all.  I did not remove the polycoat - it was too hard.  I think CZ could easily Nitride.  Would love to see them do that. 

I honestly don't think getting a NATO NSN means much.  I've never heard WHICH military adopted the P01 and what test was actually run.  We ran a thread on it a year ago.  I see people all over the www citing this, but again, not much quantitative data.  I don't think NATO has a 'T&E Unit/element.'

Just don't see why they don't do much to the frames other than harden - but they seem to last.  Someone here had 50,000 rounds.  Not bad.  But a documented test?  Good luck.

The T6 for the 7075 is the temper designation and denotes the fact it has been artificially aged. 7075 is "unstable" and continues to naturally age after it is processed so the artificial age gets it to a stable state for use in parts manufacturing without worries that its properties will change over time.
