All grades of copper have very good to excellent corrosion resistance in most environments. C101 is susceptible to the effects of corrosion if used in environments that contain halogens, sulphides and solutions containing ammonia, and oxidising acids. Forging So I'm favoring rubbing with an old tyre weight, which I havm't seen discussed either. This'll transfer some lead (or lead-antimony) into the thread grooves. I suppose some of it might get into the engine but I can't see it doing much harm. Antimony is rather high in the electrochemical series though, so galvanic corrosion may be a (theoretical at least) possibility here as well. Unlike many other metals, the yield strength of copper cannot be easily defined. The most uniform way to work it out is as 0.5% extension under load or as 0.2% offset. Usually the 0.5% extension yield strength of annealed copper is around 1/3 of the tensile strength. As copper is hardened during cold working, it becomes less ductile and the yield strength becomes closer to the tensile strength. Corrosion resistance This grade of copper is supplied in half hard temper conforming to BS EN 1652: 1998. This temper is also achieved by process cold working and subsequent annealing cycles. Annealing could be from a targeted anneal cycle or incidental annealing from welding and soldering. Corrosion resistance

Lately I use polythene sheet from the plastic bags that my breakfast steamed roll comes in, along with cheapo Taiwanese chassis grease, breaking the "never lubricate wheel bolts" rule in a third way. (THE HORROR.) Given a nut to fit in a difficult to reach spot where if dropped it would be gone, I put it in a small plastic bag. The thread could still be engaged through the plastic and, once started, the bag could be torn free, but the chances of losing the nut, while not eliminated, were much reduced.Poor Lubrication Properties Compared to Other Greases (copper grease is primarily an anti-seize grease) Sifphosphor Bronze no 8 with pure argon shielding gas, sifmig 8. Sifsilbronze 101, sif silver solder NB: Clamping force is not cleanly related to how much torque is applied to fastening the wheel bolt for all the reasons listed above about clean vs. greased threads it's impossible to *accurately* tell clamping force that will be exerted from the torquing force applied to the fastner.

Journal of Health & Pollution: "Preliminary Study of Heavy Metals in Low-Cost Jewelry Items Available in Nigerian Markets." Coppaslip is extremely hard to find in Taiwan. I did locate what I'm told may be the only tin "in the wild" in the entire country, but since it contains approximately 500,000 years supply, I didn't buy it. Buy only from trustworthy suppliers. There have been several cases of poisoning or injury because of metallic bracelets. In most cases, this is because the bracelets were made with counterfeit or harmful materials.Copper is prone to corrosion from moist ammonia environments, halogens, sulphides, inorganic acids and solutions containing ammonia ions, and oxidising acids such as nitric acid. It is recommended that for under soil use, where contamination of soil may be present or occur in future, that copper pipes are laid within plastic pipes to protect from any undetected corrosive substances. Recycling A metallic bracelet is an accessory, worn on the wrist or ankle, that is part or all metal. Examples include: If one of the types of bracelet in the trial could produce a minimum 20 percent improvement in tender and swollen joints, the bracelets will have been considered a meaningful indicator of clinical effectiveness.
