{"product_id":"alumina-coated-basket-filament","title":"Alumina Coated Basket Filament","description":"\u003cp\u003eAlumina-coated tungsten basket filaments for thermal evaporation in vacuum coating systems. A stranded tungsten wire basket carries a fused aluminum oxide (alumina) coating, so the charge sits in a ceramic cup while the tungsten underneath does the heating.\u003c\/p\u003e \u003cp\u003eThe coating keeps molten metals from wetting or alloying with the tungsten, which makes these baskets the usual choice for evaporating aluminum, gold, silver, copper and other metals that would quickly attack a bare tungsten filament.\u003c\/p\u003e \u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyles:\u003c\/strong\u003e AC-32, AC-33, AC-36, AC-37, AC-38 (4\") and AC-42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e 99.95% pure tungsten wire with an alumina coating\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse:\u003c\/strong\u003e resistance-heated evaporation sources for thin-film deposition\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eSelect the basket style above; the product photos show the dimensions of each style.
