Did you know that aluminum is the third-most abundant element in the Earth’s crust? It is also one of the cheapest metals available. Everything from soda cans to spaceships relies on this light and durable material.
Extruded aluminum is just one of the many uses of aluminum. We’ll explore the process that allows an aluminum extruder to create extruded aluminum shapes.
What Is Extruded Aluminum?
Are you wondering, “What is extruded aluminum?” Aluminum extrusion refers to the process of forcing aluminum alloy through a die. The resulting shape has a unique cross-sectional profile.
You can think of the process as being similar to pushing toothpaste through a tube. Squeezing the tube forces the toothpaste out in a cylindrical form. The process requires advanced mechanics and technology, but the concept behind aluminum extrusion is fairly straightforward.
What Is Extruded Aluminum Used For?
Engineers use aluminum extruded shapes for a wide range of industrial and construction purposes. Industries that rely on extruded aluminum include:
Extruded aluminum is commonly used to build door and window systems. Guide rails are often made from extruded aluminum. Extruded aluminum and T Slot Aluminum is commonly used to make or construct:
- Lighting fixtures
- Elevator shafts
- Internal building structures
- Car parts
- Stage assemblies
- LED fixtures
- Solar panel support structures
- Extruded aluminum channel
Extruded shapes are versatile because they can be solid, hollow (rectangular or square tubes), or semi-hollow (with a partially enclosed void). Extruded aluminum is also commonly used because the aluminum alloy is lightweight, affordable, malleable, and able to conduct electricity.

An Overview of the Extrusion Process
Each aluminum extrusion process begins with the fabrication of a steel die. This is the point through which heated aluminum is pushed. The shape of the die determines the cross-sectional shape of the resulting extrusion.
Cutting the Billet
A professional cuts the cylindrical block of aluminum alloy (billet) from a longer piece of aluminum. The metal is then preheated to 400-500 degrees celsius. The heating process makes the aluminum malleable but not molten for the extrusion process.
Rolling Metal onto the Press
Once the technician has heated the aluminum, a machine rolls it to an extrusion press. An extrusion professional then lubricates the metal to ensure that the billet and ram do not stick together. Once the machine loads the heated billet, a powerful ram pushes the metal into a container that has the die on one end.
Pushing the Billet through the Die
Pressure then pushes the metal through the die. The metal emerges from the die with a pre-determined profile. The hot metal is then uniformly cooled through a process called “quenching.”
Once the metal cools, a device called a stretcher corrects any bending or distortions that may have occurred. During the final step, the metal is cut to length and stored or shipped.

Je, ulijua kwamba alumini ni elementi ya tatu kwa wingi katika tabaka la dunia? Pia ni mojawapo ya metali za bei nafuu zaidi zinazopatikana. Kila kitu kuanzia makopo ya soda hadi meli za angani hutegemea nyenzo hii nyepesi na yenye kudumu. Alumini iliyotengenezwa kwa njia ya extrusion ni moja tu kati ya matumizi mengi ya alumini. Sisi <unk>ll kuchunguza mchakato kwamba inaruhusu extruder alumini kuunda extruded alumini maumbo. Alumini Iliyotengenezwa kwa Njia ya Extruded Ni Nini? Je, unajiuliza, <unk>Ni nini alumini extruded?<unk> Aluminium extrusion inahusu mchakato wa kulazimisha alumini alloy kupitia kufa. Umbo linalotokezwa lina profile ya kipekee ya msalaba. Unaweza kufikiria utaratibu huo kuwa sawa na kusukuma dawa ya meno kupitia bomba. Kufyatua bomba hilo hufanya dawa ya meno itoke kwa umbo la mviringo. Utaratibu huo huhitaji vifaa vya hali ya juu na teknolojia, lakini wazo la kutengeneza alumini ni rahisi sana. Alumini Inatumiwa Kwa Kazi Gani? Wahandisi hutumia maumbo ya alumini yaliyochongwa kwa ajili ya matumizi mbalimbali ya viwanda na ujenzi. Viwanda ambavyo hutegemea alumini iliyotengenezwa kwa extruded ni pamoja na: Alumini iliyotengenezwa kwa extruded hutumiwa kwa kawaida kujenga mifumo ya milango na madirisha. Mara nyingi reli za kuongoza hutengenezwa kwa alumini iliyochongwa. Aluminium Extruded ni moja ya vifaa vya ujenzi vya kawaida, na hutumiwa kwa ajili ya ujenzi wa vifaa vya taa, viunzi vya lifti, miundo ya ndani ya jengo, sehemu za gari, viungo vya hatua, vifaa vya LED, miundo ya msaada wa jopo la jua, na mifumo ya alumini ya extruded. Alumini iliyotengenezwa kwa njia ya extrusion pia hutumiwa kwa sababu aloi ya alumini ni nyepesi, bei nafuu, inaweza kubadilika, na inaweza kuongoza umeme.

Hii ni hatua ambayo alumini iliyopashwa joto husukumwa kupitia. Umbo la kufa huamua umbo la sehemu ya msalaba wa extrusion inayotokana. Kukata Billet mtaalamu kukata block cylindrical ya alumini alloy (billet) kutoka kipande kirefu cha alumini. Kisha chuma hicho huchemshwa hadi digrii 400 hadi 500 Selsiasi. Utaratibu wa kupasha joto hufanya alumini iwe rahisi lakini isiyeyeyuka kwa mchakato wa extrusion. Baada ya fundi kupokanzwa alumini, mashine huipeleka kwenye mashine ya kusindika. Kisha mtaalamu wa kutengeneza chuma hutengeneza mafuta ili kuhakikisha kwamba kipande hicho hakishikamani. Mara tu mashine inapopakia kipande hicho cha chuma, mtengenezaji wa chuma huyo anaingiza kipande hicho katika chombo kilicho na kiunzi cha chuma kwenye upande mmoja. Kusukuma Billet kupitia Die Pressure kisha kusukuma chuma kupitia kufa. Chuma hutoka kwenye die na profile iliyowekwa kimbele. Kisha chuma hicho cha moto huyeyushwa kwa njia ileile kupitia mchakato unaoitwa <unk>kuzimia.<unk> Mara chuma hicho kinapopungua, kifaa kinachoitwa stretcher kinarekebisha kupindika au kupotosha yoyote ambayo inaweza kutokea. Katika hatua ya mwisho, chuma hicho hukatwa kwa urefu na kuhifadhiwa au kusafirishwa. Aluminamu ya Extruded ni karibu na kila kitu, kutoka kwa magari tunayoendesha hadi nyumba tunayoishi.
