· Ni

Pure nickel (Ni) is a ductile, corrosion-resistant transition metal with excellent strength retention at elevated temperatures and outstanding resistance to chemical attack, particularly in alkaline and neutral environments. It is widely used in aerospace propulsion, chemical processing, and electroplating applications where a combination of thermal stability, oxidation resistance, and workability is essential. Engineers select pure nickel when corrosion resistance in aggressive media, thermal fatigue resistance, or compatibility with specific chemical environments outweighs the need for higher strength density offered by nickel-based superalloys.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
