The Advantages of Exotic Metal Fasteners And Components

As a manufacturing professional, you understand that some environments are just too harsh for a standard fastener or component. If you do nothing, it just gets worse&#;headaches from strength failure, corrosion resistance, and heat tolerance just stack up. So, what do you do?

Nearyz Resources supply professional and honest service.

Well, exotic metal fasteners and components offer enhanced performance capabilities, including superior strength, excellent corrosion resistance, and higher heat tolerance resulting in durability, safety, and value.

In exotic metals, you have a host of alloy options that beat out the more traditional materials used for fasteners and components.

What are exotic metals?

Exotic materials are high-performance alloys of stainless steel, aluminum, nickel, titanium, magnesium, and copper. They are typically an exotic alloy or have exotic elements.

What makes exotic metals stronger?

When it comes to strength, exotic fasteners and components are up to 35% stronger than your average steel materials.

So, what makes them so strong? It all goes back to the chemical properties of the material. Typically, exotic metals are composed of either a single element or a tightly controlling mixture of two or three elements that refine the properties of each metal, making them considerably stronger than other metals on the market.

For example, 17-4 PH is a steel alloy commonly used in exotic metal fasteners and components. It&#;s made up of:

• Chromium: 16.0 &#; 18.0%
• Nickel: 6.50 &#; 7.75%
• Aluminum: 0.75 &#; 1.50%
• Manganese: <1.00%
• Silicon: <1.00%
• Carbon: <0.09%
• Phosphorus: <0.04%
• Sulfur: <0.03%
• Iron: trace amount

As a result, exotic metal fasteners can be desirable when strength is the most critical design parameter.

What makes exotic metals heat tolerant?

In addition to being strong, exotic fasteners and components are also heat tolerant. Exotic metals can stand up to temperatures 600 degrees Fahrenheit or higher than your average alloy&#;s 200-degree limit&#;so they won&#;t break down as easily under extreme temperature fluctuations.

Exotic metal fasteners and components have been known to handle the highest pressure flow lines with a minimum amount of flow restriction for over 50 years. This makes exotic metal fasteners and components ideal for power generation industries that have large machinery running at extremely high pressures by utilizing exotic alloys with extraordinary ability.

What makes exotic metals more corrosion resistant?

Typically, exotic metals like nickel and chromium alloyed with steel contain more chromium than plain carbon steel. Chromium is what makes stainless steel so corrosion-resistant.

Since these exotic metal fasteners and components have more of this crucial element, they offer superior rust and corrosion resistance compared to standard stainless steel fasteners and components.

Plus, the chemical composition of exotic metal fasteners and components actually changes to prevent corrosion. When these exotic metals are exposed to oxygen, they form a thin layer of oxide film that prevents further corrosion.

So far, so good, right? However, exotic metals are worth their weight in gold (or whatever currency you prefer) when you look at what happens when it comes in contact with corrosive substances like saltwater or even salts found naturally on roads and highways.

Salt Water Corrosion Resistance: The best way to understand corrosion resistance is by looking at the pitting potential. Pitting is that rust-like corrosion that forms under the surface of the metal and causes it to turn to a dark brownish color.

For example, exotic material fasteners and components like SAE 304 stainless steel, also known as marine grade stainless steel, are a better choice of materials for products that will be exposed to saltwater.

Why do I need exotic metals?

• Does your component need high reliability?

• Does it contact corrosive fluids or gases?

• Is it subject to abrasive conditions?

• Does it require a high-yield strength?

• Is it vulnerable to age-hardening?

• Must it be acid resistant?

• Conform to rigorous industry, military, or aerospace standards?

• Perform reliably in harsh environments where conventional materials would fail?

If you answered yes to any question above, then you may be ready for an exotic metal.

Aluminum is a known material used in fasteners for its numerous characteristics that benefit various applications. But what are the lists of advantages that come with using aluminum fasteners? Can aluminum withstand the common problems encountered during fastening assemblies? Let&#;s get to know more about the features of aluminum fasteners.

RESISTANCE TO ENVIRONMENTAL EXPOSURE

It is noted that pure aluminum has reactive properties when exposed to environmental conditions. During exposure, the aluminum reacts by forming an oxide that chemically bonds to metal and keeps a layer of protection from corrosion.

ELECTRICAL CONDUCTIVITY

One of the reasons that aluminum fasteners are widely used in electrical applications is their electrical conductivity. Aluminum has a high rate of conductivity that suits most fastening that involves electricity. 

COMPATIBILITY WITH ALUMINUM MATERIALS

Since aluminum materials are prone to corrosion when paired with other metal components, the standard practice of pairing aluminum with aluminum fasteners has been inevitable. Aluminum fasteners eliminate the dangers of failure and galvanic corrosion.

ABLE TO WITHSTAND CHEMICAL CORROSION

Chemicals are mostly present in large industries that require the use of fasteners. Aluminum fasteners come in handy with applications that deal with chemical elements for their ability to withstand chemical corrosion. 

NON-MAGNETIC PROPERTIES

Since most mechanical assemblies encounter a problem with magnetism, aluminum has been known for its non-magnetic metal properties. While aluminum fasteners are highly preferred to prevent &#;clustering&#; during the installation especially when materials are handled by ferrous tools. 

CLEANLINESS OR NON-STAINING

Aluminum has great resistance to corrosion which proposes lesser maintenance and a clean finish. The presence of oxides in aluminum fasteners allows the protection it needs from corroding.

LIGHTWEIGHT

Aluminum is mostly preferred by aerospace, military, and manufacturing plants for its lightweight features. It&#;s the only metal element that is applicable to reduce weight, cost, and easier facilitation of moving the products.

ECONOMICALLY & COST BUDGET FRIENDLY

Since aluminum is widely available in many places, the cost isn&#;t usually a big deal for sourcing the material. Aluminum is highly cheaper than the common materials used in fasteners like stainless steel or even brass. And to add light, aluminum fasteners often require less to no maintenance at all. This brings it to eliminate the need for constant cleaning or keeping the assembly susceptible to corrosion.

VARIETY OF TYPES

Just like any other material of fasteners, aluminum can be freely used in manufacturing a wide variety of fasteners. There are thousands and continually expanding numbers of types of aluminum fasteners today. They can be made into special fasteners to meet the specification or requirements of their application needs.

CONCLUSION

There are numerous reasons and factors of considerable advantages to using aluminum fasteners which makes them highly versatile and effective. But it is also important to note that basic knowledge of the use of fasteners is surely needed before getting into your project for the security and safety of everyone.
