[[image]] Shear strength of A-286 Rivet blanks after heat treatment from 1000°-1400°F. for eight hours at 4 cycles. NOW-FROM DU PONT: NEW SUPERALLOY AIRCRAFT RIVET RETAINS STRENGTH UP TO 1400°F. ONE-PIECE FASTENER IDEAL FOR JET OR MISSILE APPLICATIONS Jets slashing along at 7,000 m.p.h. 40 miles above the earth-that's a picture of the near future recently drawn by a leading design specialist. To help make that vision reality, Du Pont presents the A-286 Superalloy Aircraft Rivet-the strongest Du Pont Rivet ever made. This quickly installed fastener keeps its high strength-both tensile and shear-in temperatures up to 1400°F. (See graph on shear strength above.) In fact, Rivets actually increase in strength as they're "cycled," just as they are in jet applications And, of course, the A-286 Superalloy has all the family advantages of a Du Pont Rivet. A one-piece fastener with nothing to shake loose, it is easily set-open or blind-from the head side only. No bucking bar or after-finishing is ever necessary. Superalloy is a metal combination specially designed to meet the needs of superseeds.Sturdy, durable, high heat- and corrosion-resistant, it is an ideal composition for an Aircraft Rivet. In jet engines, guided missiles or any job where high strength with high heat resistance is required, use the new Du Pont A-286 Superalloy Aircraft Rivet.*To obtain information and specifications on this amazingly advanced development write: E.I. du Pont de Nemours & Co.
