Polyester powder coating protects metals from corrosion and harsh weather, and retains its color for years. This coating can be applied any metal, but typically steel or aluminum. For the best protection, steel parts are galvanized first, then painted using this process. For exterior parts, ensure that the powder meets AAMA 2604 standards for ...

Magnetic Sheet Metal Separators. Separate stacked steel sheets without prying, scratching, or bending them. These separators have a magnet which causes your stacked sheets to fan out. When you remove the top sheet, the next sheet automatically moves up. Separators have two nonmagnetic bars to keep plates moving freely.

Once this inert separator was lost, galvanic corrosion caused the carbon steel support system to fail. Unfortunately, this is a common theme among lots of these prominent examples: designers often fail to realize that if a cladding or roof system is designed to last throughout the building's life, then the same should apply to the structural ...

The further apart the metals are on the corrosive scale, the stronger the galvanic reaction between the two. Similar metals have little effect on each other. For example, aluminum is considered an active metal and stainless steel is considered inactive. In a corrosive environment, aluminum corrodes at a higher rate, but the stainless steel ...

More About Magnetic Separation. Last month, we wrote about how magnets are assembled for magnetic separation applications – attracting iron, steel, or other ferromagnetic bits to get contaminants out of other materials. It was a great example of some specific ways that magnets are selected and assembled for this task.

We installed a steel stringer/steel riser stair with aluminum threads. In the spec it said to use a rubberized tape as a galvanic separator for the dissimilar metals. As a alternate to the spec we epoxy coated all the contact points of the aluminum thread. The stringer and the riser are were painted with Mercury m-12 paint.

Conversely, if you use aluminum to attach a large sheet of stainless steel, the aluminum life will be dramatically shortened. Albany County Fasteners recommends the use of neoprene EPDM or bonding washers in between stainless fasteners and aluminum materials, the neoprene forms a barrier in between the metals, preventing corrosion.

A hob separator plate is a piece of sheet metal installed on the underside of your hob. It provides a protective barrier between the hob cabinet and the underside of the hob. It separates your cabinet storage space from the cooktop. This means there is no risk that you can touch the hob from below when using the cabinet or drawer.

Since the area of copper is larger than the aluminum's, there is greater cause for concern and prevention of harmful corrosion. When carbon steel is employed as reinforcing material or steel anchors in conjunction with aluminum-framed window systems, separation is required to prevent galvanic corrosion.

Corrosion develops when two dissimilar materials are combined in a corrosive electrolyte. This can occur when certain materials such as aluminum are in contact with stainless steel. When aluminum makes contact with stainless steel fasteners, corrosion can occur. However, the two metals can be used together, as this guide shows.

Q: Why does corrosion occur between anodized aluminum and steel? A: Aluminum is a reactive metal (unnoble) which should have a low corrosion resistance, according to thermodynamics. The high corrosion resistance found on aluminum, nevertheless, is due to the presence of a thin, compact film of adherent aluminum oxide on the surface.
