· JVASP-65298· K4ZrBe

K4ZrBe is an intermetallic compound combining potassium, zirconium, and beryllium—a research-stage material rather than an established commercial alloy. This composition lies within the broader family of lightweight refractory intermetallics, which are of interest for applications requiring low density combined with structural integrity at elevated temperatures. The material remains largely experimental; its potential applications would target aerospace, defense, or advanced thermal systems where weight reduction and high-temperature performance are critical, though practical implementation faces challenges around manufacturing scalability, cost, and material characterization that are typical of multi-component intermetallic systems.

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.
