  • Durmalon: An Alternative to Cadmium (.pdf)
    Cadmium has been applied to numerous components of land, sea and air weapon systems and NASA systems for many years, due to its desirable functional qualities. However, Cadmium is a toxic metal and a known carcinogen. In addition, Cadmium is plated from an aqueous bath containing cyanide salts
  • Total Cyanide Analysis in Cadmium/Cyanide Bath
    Total cyanide may be measured directly with an Iotron Cyanide electrode in cadmium/cyanide baths. The measurement is based on the stability of the cadmium-cyanide complex. As cyanide concentrations may vary widely, the following procedure should be used as a general guide.
  • Finishes and Coatings
    Fastener coatings or finishes improve appearance, increase corrosion resistance, and provide lubricity. Zinc, cadmium, tin, nickel, and chromium coatings are most common for fasteners. Zinc is preferred for industrial atmospheres. Cadmium is best in marine atmospheres but is more expensive than
  • Simultaneous Metal Treatment and Hexavalent Chrome Reduction
    A well known military metal finishing operation in Pennsylvania was having trouble treating hexavalent chromate rinses that also had cadmium in them. Our team of experts set the system up to treat both the hex chrome and cadmium bearing rinses in the same tank. The Aquapure I-300 was used
  • What is RoHS Compliance?
    RoHS (Restriction of Hazardous Substances) is a directive from the European Union (EU) that restricts the use of six hazardous materials commonly found in electrical and electronic products. In particular, it specifies maximum levels for lead, mercury, cadmium, hexavalent chromium, polybrominated
  • Hex-chrome-free process turns the screws on corrosion
    including bolted or riveted joints. With new ELV standards, the auto industry must look at lead, cadmium, and hexavalent-chromium replacements to reduce and/or eliminate the use of these materials in coating processes. The ELV has several objectives for primary
  • Medical Device Link .
    Touch and Go: Nanothin Film Makes Cancer Tissue Detection Easier To make the sensor, researchers deposited alternating layers of gold and cadmium sulfide nanoparticles, separated by insulating layers of polymer that are about 2 or 3 nm thick, to create a 1-cm2 piece of film that measures 100 nm
  • Nickel Metal Hydride Batteries; It's About Time
    Every industrial hygienist at one time or another has felt the bite of nickel-cadmium batteries. Certainly the venerable NiCad power source has served us well in every king of industrial hygiene instrument from personal monitoring pumps to multi-gas monitors. They are lightweight, reusable
  • Traces of Heavy Metals in Toys
    (Restriction of hazardous substances) has come into force, there are strict limits for the amount of heavy metals, such as lead, cadmium and mercury, allowed in consumer goods.
