Aluminum and its alloys are normally protected by an ultra thin surface oxide film (known as the passive film) and are reasonably resistant to corrosion in environments having a pH of 4~8. In acidic or alkaline environment, the oxide film is no longer stable and aluminum corrodes actively, forming soluble corrosion product (Al3+ or AlO2-).

Hundreds of samples of aluminum foil have been stored in the laboratory for various periods of time up to 10 years with no visible signs of deterioration." American Society of Heating & Air Conditioning Engineers' Journal Section Aluminum is highly resistant to the effect of corrosion... Aluminum is constantly being used where it is exposed to weather, salt spray and other conditions, which would adversely affect most metals." The United States Rubber Co.

Met-Tile panels are made of Zincalume™ coated steel that provides excellent corrosion resistance for most applications. In oceanfront climates (i.e. within 1800 ft. of a salt water body) or other unusually corrosive environments, an aluminum substrate is recommended in place of steel. Visit the Met-Tile aluminum page for further instructions.

MIX OF METALS ? The Hydrovane is well engineered. A ten or twenty year old unit should look much like a new one. Once you get a chance to have a hard look at one you can identify that separation between metals has been provided for at all critical joints ? lots of plastic/delrin sleeves. All the castings are either LM5, a high magnesium aluminum alloy of superior marine grade. Those castings are all anodized ? again high quality and designed to minimize electrolysis.

Have you ever heard of goat-lick tea? What is it? Where can I get some? Please let me know. This has been driving me crazy!

All aluminum rings out in a very unique way. It almost has a natural chorus to it. For as many highs it adds, it adds as many lows and mids. It does what wood does but only better in my opinion.

NdFeB magnets are susceptible to corrosion. The 'Fe' in the name stands for Iron, and it rusts! Many of our magnets come with a Nickel, Zinc, Gold or Epoxy coating to protect them from moisture. If the coating is damaged (frequently the case with surplus magnets) the magnet could rust if exposed to water or humidity. If this is a concern to you, you can easily add another layer of protection by dipping the magnet in epoxy or plastic coating.

quot;Coagulation" is an important water treatment process for its human consumption, because there is no another way of eliminating the turbidity of raw water. This technology requires the addition of substances that through a physico-chemical mechanism permits the gathering of small and light particles. The added particles produce bigger ones (called "floccules") that are easily eliminated by decantation.

It takes 1218 degrees to melt the aluminum and 717-737 degrees for our material to melt and penetrate the aluminum.

Thermal Window frame and an ordinary aluminum window frame on extremely cold dry ice to illustrate how cold is transferred through the frame. Notice that the ordinary aluminum window frame, shown on the left, is completely covered with frost. Now look at the West-Prime Thermal Window Frame on the right. Our thermal barrier resists the transfer of cold from the outside to the inside of the frame. And, of course, the same thermal barrier slows the transfer of heat in summer.

No, in fact, we would recommend against plating aluminum wheels. At any time, a rock pit, scrape or deicing/harsh chemicals can break the seal between the plating and the alloy, allowing corrosion to start, resulting In bubbling under the chrome surface, then ultimately peeling. Solution, those wheels can be polished to as good or better of a finish than chrome, and with a little bit of maintenance, they can be kept that way.

Yes, I get a lot of questions about Azomite. It is safe for human consumption. I recommend it because it is a natural, inexpensive mineral supplement. Tests have never been done on humans and won't be because the FDA won't allow it. There have only been studies with animals and it is a good mineral supplement for animals. It does contain aluminum, but it is also rich in silica, which counteracts the aluminum.

There seems to be three camps on this subject. One thought is to use a wax sealer, such as Eagle 1 ("waxes as you dry”). Another is to do a light touch-up polish every couple of years, and the other is use a wipe on/wipe off sealing polish, such as the one available from Rolite. All methods have their supporters.

We designed our aluminum rings to have all of the same great characteristics of our nylon rings. They are smooth, strong, safe and weld-free. They are lightweight and come in nine great colors. The nylon and aluminum rings come in slightly different sizes. The nylon rings are thicker, and easier to adjust. The aluminum rings are grippier, and fancier looking. The colors are slightly different. The nylon rings are slightly more durable.

Though we touched on the subject at the beginning of the FAQ’s, you will find this is no longer a popular option as the handling of messy, used filters combined with the cleaning process turns off most people. Reusable filters must be cleaned and maintained as much as 2-3 times more frequently than disposable pleated air filters. Pay special attention to the removal of all moisture before reinserting the reusable air filter back into the HVAC system.

There has been a good deal of "discussion" as to whether or not the use of aluminum in brewing contributes to Alzheimer's disease. Thanks to Oliver Weatherbee for providing to following: Aluminum has NOT been linked to Alzheimer's disease. The following is taken from "Frequently Asked Questions About Neurological Problems" at The Department of Neurological Surgery of The Cleveland Clinic Foundation (http://www.neus.ccf.org/patients/faq.

Aluminum sulfate acidifies (reduces the pH of the soil). Some plants have a high requirement for microelements, which are more available in the acid pH range 4.5 to 5.5. These acid preferring plants include: Azaleas, Rhododendrons, Holly, Birch, Blue Hydrangeas, Blueberries, Begonias, Camellia's, Fuchsia's, Gardenia's & Magnolia's. Gardeners realize that the key to increased yields and a successful garden is knowing their soil pH and nutrient levels.
