The "See also" section has one entry, to Northwest Airlines Flight 421, which makes no mention of aluminum 7075, nor any alloy. Perhaps there was some connection in a past version of that page, but there seems no reason for the link currently. 173.180.151.52 20:34, 23 February 2018 (UTC) anon
The purpose is to reduce the file size of torrent files, which reduces the burden on those that serve torrent files. A torrent file using Merkle trees does not have a pieces key in the info list. Instead, such a torrent file has a root_hash key in the info list. This key's value is the root hash of the Merkle hash:
Torrent poisoning is intentionally sharing corrupt data or data with misleading, deceiving file names using the BitTorrent protocol.This practice of uploading fake torrents is sometimes carried out by anti-infringement organisations as an attempt to prevent the peer-to-peer (P2P) sharing of copyrighted content, and to gather the IP addresses of downloaders.
Another application for the 7075-series alloy has been in connecting rods used in drag racing engines. Aluminum rods do not have the fatigue life of forged steel rods, but have less mass than their steel counterparts, resulting in lower mechanical stress during periods in which an engine is operated under full-throttle, high-RPM conditions.
Many metals and thermoplastics can be welded, but some are easier to weld than others (see Rheological weldability). A material's weldability is used to determine the welding process and to compare the final weld quality to other materials. Weldability is often hard to define quantitatively, so most standards define it qualitatively.
7068 alloy is a 7000 series aluminium-zinc alloy registered with the US Aluminium Association and produced to AMS 4331 (chemical composition and mechanical properties) and AMS 2772 (heat treatment). 7068 alloy ‘A’ and ‘B’ tensile data and fatigue properties have been ratified for inclusion in MIL Handbook 5 / MMPDS.
Solderability when using lead-free alloys can differ significantly from solderability when using lead based alloys. Noble metals may be easy to solder but they have brittle joints. The metals in the good category require a large amount of heat therefore oxidation is an issue. To overcome this a flux is required.
