· JVASP-907· Kr

Kr is a transition metal with moderate elastic stiffness and density, positioned in the middle range of structural metals. It is primarily used in specialized aerospace, automotive, and high-strength structural applications where a balance between weight and rigidity is required, as well as in chemical processing equipment and corrosion-resistant components. Engineers select this material when performance envelopes demand intermediate strength-to-weight ratios or when corrosion resistance and thermal stability are critical factors over materials that are either too heavy or lack sufficient stiffness.

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.
