anodized
Anodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.
The process is called anodizing because the part to be treated forms the anode electrode of an electrolytic cell. Anodizing increases resistance to corrosion and wear, and provides better adhesion for paint primers and glues than bare metal does. Anodic films can also be used for several cosmetic effects, either with thick porous coatings that can absorb dyes or with thin transparent coatings that add interference effects to reflected light.
Anodizing is also used to prevent galling of threaded components and to make dielectric films for electrolytic capacitors. Anodic films are most commonly applied to protect aluminium alloys, although processes also exist for titanium, zinc, magnesium, niobium, zirconium, hafnium, and tantalum. Iron or carbon steel metal exfoliates when oxidized under neutral or alkaline micro-electrolytic conditions; i.e., the iron oxide (actually ferric hydroxide or hydrated iron oxide, also known as rust) forms by anoxic anodic pits and large cathodic surface, these pits concentrate anions such as sulfate and chloride accelerating the underlying metal to corrosion. Carbon flakes or nodules in iron or steel with high carbon content (high-carbon steel, cast iron) may cause an electrolytic potential and interfere with coating or plating. Ferrous metals are commonly anodized electrolytically in nitric acid or by treatment with red fuming nitric acid to form hard black Iron(II,III) oxide. This oxide remains conformal even when plated on wiring and the wiring is bent.
Anodizing changes the microscopic texture of the surface and the crystal structure of the metal near the surface. Thick coatings are normally porous, so a sealing process is often needed to achieve corrosion resistance. Anodized aluminium surfaces, for example, are harder than aluminium but have low to moderate wear resistance that can be improved with increasing thickness or by applying suitable sealing substances. Anodic films are generally much stronger and more adherent than most types of paint and metal plating, but also more brittle. This makes them less likely to crack and peel from ageing and wear, but more susceptible to cracking from thermal stress.
I have an excellent condition, rather rare PWS MK114 Alpha in anodized FDE. The Alpha model was released with slight differences to the other PWS models and the factory anodized FDE ones were a more limited release than the black models.
The differences in the Alpha include a more robust rail...
I have 8 Anchor Harvey Anodized 80% lowers.
No trades on these. All sales will be conducted at Home Depot off Airport way in Portland or shipped to your Oregon address for $10ea.

One lower I received today has a pretty good blemish on it and wondering if there is anything I can do on my end.
It appears to be more than just surface marks. Almost like the anodizing in those areas is extremely thin and raw metal is showing through. It's smooth, and I wiped it with a damp...

Selling two new AR15 80% lowers. They are anodized and have safety selector markings (safe/fire). Ordered them in 2019 and don’t recall the manufacturer.
$85 each.
I bought this beautiful example of rugers MKIV 22/45 Lite along with a purple one but I can’t bring myself to shoot both. I am looking to sell my unfired gold anodized model, to buy something else that I don’t have.
Included is 2 magazines and 800 rounds of federal .22lr in a range pack.
All items new in box. Face to face Eugene/Springfield preferred, but willing to ship. Trade values negotiable.
Please PM trade offers.

- 9mm Luger ammo

1. AR15 9" Quantum M-LOK Handguard - Anodized Black (BLEM) Traded, images...
Up for sale is a ruger MK4 22/45 lite. Taking it down is easier then an AR-15. Press the button on the back and it comes apart. It’s sweet.
Reloading is the worst part about it since it runs through ammo so quick with how fun it is. I bought 10 mags to remedy that!
So you’ll get the pistol, 10...
