Electronic Metals and Alloys

• Electronic Metals and Alloys possess exceptional
  electrical, magnetic, surface and
  corrosion-resistant properties that play major
  roles in everyday electronic applications such as
  computers and smart phones.
• Materials that play a major role in the
  electronic metals and alloys categories include
  200 Series Nickel.

• Nickel 201
• Nickel 205

• The metals and alloys that go into both consumer-
  and industrial-grade electronics must be
  flexible, versatile and able to be manipulated
  with extreme precision. Heat is another key
  concern with electronic equipment, which means
  any alloys used have to be able to resist the
  effects of high temperatures. Finally, the metals
  must be able to withstand corrosion. Combined,
  these factors can significantly impact a piece of
  electronic equipments operability and longevity.
• For many electronic and communication components,
  engineers will use commercially pure, low-alloy
  nickel. Compared to nickel alloys, commercially
  pure nickel maintains high electrical and thermal
  conductivity. It also has good ductility and
  malleability, both of which play an important
  role in the manufacture or repair of sensitive,
  small components that require much precision.
• Nickel Alloy 200 is another electronic grade
  alloy thats often used in electronic
  applications. One of the worlds toughest metal
  alloys, Nickel Alloy 200 maintains very good
  resistance to corrosive and caustic environments
  and acids, including hydrochloric, sulfuric and
  hydrofluoric.
• This alloy is commercially pure (99.6 wrought
  nickel) and can be used across many different
  applications due to its good mechanical
  attributes and resistance. Nickel Alloy 200 also
  has magnetic and magnetostrictive properties
  along with the essential electrical and thermal
  conductivity requirements for electronic
  components.
• Tantalum Takes Center Stage
• A highly stable metal thats virtually immune to
  chemical degradation at low temperatures,
  tantalum is another popular choice for engineers
  and designers involved with the production of
  electronics. The metal also demonstrates high
  levels of corrosion resistance (when it comes in
  contact with moisture or air) and forms a thin,
  protective oxide layer upon exposure to the
  atmosphere.

• Used in various alloys, tantalum adds high
  strength, ductility and a high melting point to
  those formulas. Over 50 of the worlds tantalum
  is used to make electrolytic capacitors and
  vacuum furnace parts. It can also be found in
  electronics, cell phones and micro-electromechanic
  al systems (MEMS) technology, or the tiny
  integrated devices and systems that combine
  mechanical and electrical components.
• As the miniaturization trend continues, the use
  of tantalum in electronics will likely increase
  due to the metals very high working temperatures
  (although the metal itself is much heavier than,
  say, tungsten). Because its corrosion-resistant
  to hydrochloric, sulfuric and other acids,
  tantalum is also used frequently by large
  chemical companies (e.g., to make the tubs that
  the companies mix their chemicals in).

• Selecting the Right Metal or Alloy
• When selecting electronic grade alloys,
  procurement professionals and engineers should
  carefully consider the specific application that
  theyre working on and the environment that the
  device or equipment will be operating in. This
  will determine your metal purity requirements,
  which is a key consideration due to the fact that
  within the Nickel Alloy 200 series there are
  various purity levels.
• For example, Nickel 290, a grade of nickel made
  by a powder-metallurgy process, offers very high
  purity levels that reach as high as 99.95. Often
  used in electronic applications such as
  components of hydrogen thyratrons and for battery
  applications, Nickel 290 has a low annealing
  temperature that makes it superior to other forms
  of nickel as a substrate for precious-metal
  cladding.
• Finding the right electronic grade alloy for your
  specific project is critical to ensuring proper
  functionality, heat-resistance and
  corrosion-resistance for that application. To
  guarantee the best match, start by carefully
  assessing your own project needs and then
  comparing them against the properties and
  specifications of each prospective metal alloy.
