Please forgive any resultant repetition, failures of chronological order, or what may look like readers disrespecting previous responses -- those other responses may not have been on the page at the time I have a callout for AMS [affil. B Type 2 electroless nickel.

I don't have the spec. Can someone help me? I need to know what the type 2 refers to - thickness, phos content, heat treatment? AMS [affil. Straight nickel-boron is covered by AMS [affil. Most companies won't touch thallium bearing solutions - check out the health concerns associated From one websource: "Exposure to high levels of thallium can result in harmful health effects.

Studies in people who ingested large amounts of thallium over a short time have reported vomiting, diarrhea, temporary hair loss, and effects on the nervous system, lungs, heart, liver, and kidneys. It has caused death. A study on workers exposed on the job over several years reported nervous system effects, such as numbness of fingers and toes, from breathing thallium. Hello Stephen! N-T-B has 2. The electroless nickel plating process occurs from a chemical reduction of the nickel ions within the electroless nickel solution onto a metallic substrate rather than deposition of the ions from an applied current.

As a result, the electroless nickel deposit is free of many of the problems associated with traditional electrolytic nickel including edge buildup and non-uniform coating. Electroless nickel deposits are extremely uniform, corrosion and erosion resistant and provide excellent lubricity.

APT offers loose-piece barrel, rack and vibratory electroless nickel plating on nearly any metallic substrate including nearly any ferrous, cupreous and aluminum alloys as well as many exotic alloys. The electroless nickel phosphorous content affects the properties of the deposit significantly including hardness, corrosion resistance and magnetism. Below is a brief overview of the electroless nickel plating provided by APT:.

Electroless nickel plating is a unique plating process that does not require an external source of electrons for deposition as in traditional electrolytic plating. Rather, electroless nickel is a nickel-phosphorous alloy deposited by a chemical reduction reaction from hypophosphite on a catalytic substrate without the application of external current.

Since there is no applied current during deposition, electroless nickel plating deposits are free from the common nonuniformity of traditional electrolytic deposits and can cover even extremely complex geometries with excellent uniformity see: What are the differences of electroless nickel over traditional electrolytic nickel in our Technical Library Plating Topics section.

Any portion of a part that is equally wetted by the electroless nickel solution will plate uniformly including interior or ID features. It is important to note that continual solution flow is required to maintain consistent deposition rates.

As such, blind holes small inner diameters of tubing or fittings will often have reduced plating thickness.
