Литые изделия из металла в быту - мясорубки, тиски для слесарных работ, "голова" молотка. Штамповка металла- это сковородки, кастрюли, чашки. Фрезеровка и шлифование- это дверные замки, сложные механические части швейных машин и кухонных комбайнов. Токарная обработка очень редкий вид на сегодня, но можно встретить в быту элементы дверных ручек. Сверление применяется практически во всей бытовой технике, в изготовлении кастрюль и сковород. Кружки из нержавеющей стали выполнены из листового металла, он в свою очередь сделан методом горячего проката. Свойства металлов- прочность, устойчивость к воздействию температур, пластичность при нагревании. Из металлов изготавливают очень прочные конструкции, пролеты мостов, поезда, корабли. Металлы выдерживают большие температурные нагрузки( самолёты,подводные лодки). Металлы при нагревании становятся более пластичными, это используется в производстве листов из металла.
