AOTCO works with a variety of metals to create plating that is not only compatible with our commercial customers’ needs, but align with the budgets of their projects. From silver to nickel to copper to gold, we work to create plating with our high quality assurance program that ensure a low rejection rate from our […]
To be prominent in the metal finishing industry, it’s essential to hold national accreditations that solidify the pride and professionalism a company has in their product. ISO 9001:2008 & AS9100 Quality Management Systems focuses on quality policies and objectives to meet consumer requirements. This system tracks the organizational structure, policies, procedures, processes, and resources needed […]
AOTCO has developed expertise in a wide variety of different elements, alloys, and metal mixtures for use in metal finishing. We love working with new and useful compounds, and if you do not see something on our materials list, please contact us. We enjoy the challenge of working with new things and broadening our catalogue.
In our series of materials on our materials page is Copper-tungsten alloy. Strictly speaking, CuW is a pseudo-alloy of copper and tungsten. Copper and tungsten are not mutually soluble. As a result, the alloy is made of tiny particles of one metal intermixed in a matrix of the other. In other words, metal matrix composite rather than a true alloy. Naturally, the resulting alloy contains properties unique to both elements. It is heat resistant, ablation-resistant, thermally and electrically conductive, and very easy to machine. This makes it ideal for a large number of metal finishing applications.
AOTCO is proud to announce that it has registered and been approved under ITAR as a Metal Finishing Contractor. What this means for our customers is that AOTCO is continuing to grow into new territories and to develop ever more sophisticated technology and development. ITAR, or International Traffic in Arms Regulation, is required registration for any manufacturer, company, broker, etc, of defense services or technical data defined by the United States Munitions List. Simply put, the United States military has put together a list of weapons that require special license or approval to export. Everything from guns and ammunition to tanks, aircraft, submarines, and nuclear weapons are on this list. Any sort of weapon or equipment that the military does not want being sent overseas is on this list. Any company that makes or sells any item or component on the list has to register with ITAR. The point of ITAR is so the government knows who makes what. AOTCO has been metal finishing for military and aerospace companies for a long time, and ITAR registration is necessary in order to further expand our business into these fields.
AOTCO uses a large number of materials and substrates to meet the diverse needs of our customers. Our Material/Substrates page has an entire list. Contact us if, for any reason, there is a materials that is not listed. We enjoy the challenge and opportunity to work with new materials. In recent blogs, we have been talking about some of the unique compounds that have revolutionized metal finishing and related industrial applications such as defense, aerospace, or electronics. Some of our customers might not be familiar with Beryllium Oxide. This compound has a number of useful properties and especially shines in electronic applications where its high thermal conductivity and notable electrical insulation makes it particularly useful. It also has a number of uses in rocket engines, ceramics, high performance microwaves, vacuum tubes, magnetrons, and gas lasers.
At AOTCO, we offer a wide range of materials and substrates from which to choose. For a full list, please visit our Materials/Substrates page. If there is a material that you would like to work with that is not on the page please call and speak with us. We relish the chance to work with new and interesting materials and for new and interesting ways to satisfy our customers. Some of the materials are familiar to most people. The application of bronze, as an example, has an entire age named after it. Other materials, such as Aluminum Silicone Carbides (AlSiC), might be new. AlSiC is a metal composite consisting of a ratio of Aluminum matrix with silicone carbide particles. A metal matrix composite is a composite material of at least two constituent parts. The first being aluminum. Aluminum makes up anywhere between 37%-63% depending on the formulation of AlSiC and the other constituent is the Silicone Carbide. The varying ratios of Aluminum to Silicone Carbide can be used to match the thermal expansion of gallium arsenide, silicon, indium, and a host of other materials, many of them particularly important in the electronics field.
On our website, you will see an extensive list of metals commonly used in scientific and industrial applications. At the top of the list, in alphabetical order, is AlBeMet. AlBeMet was developed by Materion Corporation. AlBeMet is an aluminum-beryllium metal composite. It is 62% commercially pure beryllium and 38% pure aluminum. It is a powdered substance that is consolidated by Hot Isostatic Pressed, Extruded, and Rolled Sheet. It combines the high modulus and low density found in Beryllium metals with the easy fabrication and mechanical properties of Aluminum. This trademarked material has numerous and remarkable properties. The powder organizes aluminum between beryllium dendrites producing a uniform microstructure. It has a very low thermal expansion coefficient but a high thermal conductivity. The high Modulus–to –density ratio is 3.8 times of that of aluminum or steel and has twice the typical fatigue limit of aluminum. Combined with the limited thermal expansion and thermal conductivity, this makes this material ideal for circuit boards. AlBeMet also has applications in aerospace and satellite technology. It is easy to use, versatile and can be manufactured with the same metal finishing techniques as aluminum.
Invar is a nickle-iron alloy that is known for its low coefficient of thermal expansion. This remarkable discovery is 36% Nickle and 64% Iron. Charles Guillaume developed it in 1896 and called it Invar, short for Invariable, because it is a negligible expansion due to a change in temperature. He won the Nobel Prize for this discovery in 1920 because his discovery made it possible to make extremely accurate scientific instruments. For over a hundred years, Invar has been useful for its unique properties. Invar is still used extensively in a wide variety of industrial and scientific applications. We are pleased to be able to offer Invar as one of our many metalworking services.
