· JVASP-91895· Mg7Cr

Mg7Cr is an intermetallic compound composed of magnesium and chromium, representing a research-phase material within the magnesium alloy family. While not widely commercialized, this compound is of interest in materials science for exploring lightweight intermetallic systems, particularly where magnesium's low density combined with chromium's strengthening and corrosion-resistance contributions could offer performance benefits. Engineers would consider this material primarily in experimental applications or advanced development programs targeting extreme weight reduction or high-temperature stability, though its brittleness and processing challenges relative to conventional Mg alloys typically limit current industrial adoption.

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.
